OK I was trying to work out the infedelity bit

Men in general are far more violent than women. But not many men are anti-men because of that.
Homophobia is nothing to do with anybody being flamboyantly gay.
Yes there are MANY WRONGS with stereotyping.
And define "gay voice".
Because I am straight, however my voice if I do not focus, can get high pitched. I do not see something wrong with it, because that is how my phonetic cords are.
Hell I could pursue a career in opera as a Countertenor, making more money than as a software developer. Because is rare.
But again due to social stupidity, I have to focus when I am talking to make my voice as heavy as possible.
Ok, so you're not like everyone else. Some people are bald, others have big noses. Get over yourself, it's how the world is.
A gay voice is far more than high pitched. You know what I mean.
What you're trying to say is "camp", which has little to do with being gay. That said a disproportionate amount of gay men do act camp compared to straight men. How that justifies homophobia however...?
As for black people being more prone to violence it's mostly because of socioeconomic factors and nothing to do with the colour of their skin. Is a black person growing up in a millionaire family more likely to be violent than a white person in the same situation? No, of course not.

I literally don't understand how or why people are racist or homophobic. It just doesn't make sense to me and it sickens me to think some people are.
Can somebody please enlighten me?
Well racism is now a catch-all for literally anyone you might have a disagreement with and homophobia is just men (and i guess women) who are probably themselves curious about it but need to show they're the best lad/ladette there is.
That depends on what you mean by "racist" and "homophobic". There's a great deal of irrational prejudice, hypocrisy and bullying in accusations of either.
I'll assume for the sake of argument that you do mean bona fide irrational prejudice on the basis of "race" or homosexuality.
My first question is why you single out just those particular irrational prejudices. If you understand how or why people have irrational prejudices against other biological groups, how can you not understand those? If you don't understand irrational prejudices against any biological groups, why single out just those ones?
I'll assume for the sake of argument that you're saying you don't understand irrational prejudice against any biological group and singled those out solely because they're currently unfashionable.
There's a whole slew of reasons;
Group identity. A person isn't going to be irrationally prejudiced against a biological group unless they put a group identity on themselves by some aspect of their biology. If they don't believe in biological group identity, they can't have irrational prejudices based on that belief. Sadly common. Maybe universal. Maybe it's hardwired into primates. Maybe all animals.
Conditioning, especially in childhood and adolescence. People strongly tend to believe what they're conditioned to believe. If they're really heavily conditioned, they probably won't even think about thinking differently. Random example 1: Mary Somerville was never a member of the Royal Society. She was qualified, but the idea of her becoming a member didn't occur to anyone and that includes her. Women weren't members in those days and that was how it was to such an extent that nobody even thought to question it. Random example 2: When voting reform groups started to form in the UK in the very early 1800s, the mainstream of voting reform was going for universal adult suffrage. At the time, a few percent of men had the privilege of voting and a couple of percent of women technically had the privilege of voting but as far as I can determine whether they actually did was never tested. By the early 1810s, voting reform groups had been formed in most places in the country and it was becoming quite mainstream. It was still mostly men doing the campaigning, but an increasing number of women were joining. The groups voted internally on what the group did, positions in the group, etc. There's an eyewitness account from a meeting of one group in which a member of the group raised the suggestion that the women in the group should vote too. Nobody had thought about it before, including the women. In a group that existed specifically for the purpose of lobbying for all adults to have the right to vote in all elections.
Propaganda. It works, that's why people use it and have done for at least all of recorded history.
Simple answers. People tend to like simple answers and an identifiable group to blame is a very simple answer.
Sense of belonging. Biological group advocates and advocacy groups foster a strong sense of belonging. Many people need to feel they belong to something. I've read an interview with someone who joined a white supremacy group primarily because they were nice to him and made him welcome, made him feel that he belonged. He wasn't particularly racist, at least not to begin with.
Low self-esteem. Ties in with belonging, of course.
Just an ******** looking for an excuse to be an ********.
Probably some more I can't think of off the top of my head.
Men in general are far more violent than women. But not many men are anti-men because of that..
Just as a side point here about it being an "irrational" viewpoint.
If i asked you to (in broad strokes not every individual) summarise and order the achivements of each race on earth
Who would be your top 5?
