Going round in circles, so I'll post my rebuttals to his 'opinion' of homosexuality in one post and leave it that....
It's not natural
Same sex relationships, be it kinship or sexual are abundant in nature. Sheep, for example, 10% of sheep are exclusively gay which is the same proportion in humans.
Only one species though displays homophobic tenancies which is humans, so if anything it is that which is unnatural.
However, if by 'not natural' you mean because it doesn't produce children then you must also hate infertile people having sex, contraception, women having sex when they're not on their period, heterosexual fellatio and anal sex etc why pick on gay sex?
It's not normal
If you're talking statistically, the words you are looking for are 'not usual'. The word 'normal' just means 'expected'; and in a species of highly evolved mammals (given what we know from above) you would expect to see a proportion of homosexuality, ergo it is normal.
Think of it this way, a Television works the vast majority of the time, but you wouldn't describe a TV breakdown as 'not normal'*
*I'm only making a point about the use of the word 'normal' and NOT comparing gay people to broken televisions...before anyone twists it!
It's Disgusting and Vile
Both of those words are subjective, which means personal to you and not an objective statement. You may not like the though of partaking in an act of gay sex, but you may not like the thought of eating jellied eels either and you don't give people that do eat them a hard time or care if they change their dietary choices or not.
Furthermore, anal sex is far more prevalent in heterosexuals than homsexuals; and many gay couples don't even practice it.
Ultimately, homosexuality is
two people loving each other and surely that supersedes your
hate for them [which leads me on to my next point].
I hate the sin, I love the sinner
Falling in love with someone of the same sex is part of that person, it is not a separate entity. It's as biologically part of them as their gender, hair or eye colour. It is not an 'opinion' or a 'life choice'; it is nature not nuture. If you 'hate their sin' you hate a part of who they are.
They can be 'healed'
So called 'Reperative Therapy' maybe big business in the still Christian dominated United States, it has an awful 'success' rate and is a form of brainwashing that tells the recipient that every time they feel affection for a member of the same sex it is a sign that they are 'ill'.
I find it bizarre that someone who cares so much for the unemployed they are willing to post walls of text about how evil the Workfare scheme is wants to encourage gay people to enter a scheme that at best doesn't work and at worse causes the person serious psychological harm?
Edit:
Let me make it clear that it's not a request. We're not going to tolerate people inciting hatred against anyone's sexual orientation here.
