Islam is not a race it is a Religion
Islam is a religion, the shared belief and culture of which makes the islamic people a race, check your definitions again. It is perfectly legitimate to desribe someone who openly dislikes Islamic people as a racist.
Even as someone earlier pointed out racism is strictly thinking one race is better than another, obviously thinking one race is worse has the same affect.
If you disagree with an islamic or muslim person on any issue your racist, dont you know?
If you disagree with an islamic person on any issue because they're a muslim, then yes you are a racist.
If you generalise the entirety of islam based on the words or actions of a few then yes you're probably racist.
If you think that your country is at risk from a massive minority of the population who happen to in some cases be born outside of the country, then you're probably xenophobic, however if the only ones of these people you're worried about are a specific race (Islamic) then once again, you're a racist.
If you have genuine concerns, raise them, but at worst raise them of islamic extremists, and preferably of extremists in general, and then you might get somewhere.
Until you realise that probably even all extremists aren't the same (see four lions), and definitely not all people who class themselves as a certain religion are the same, then I don't have much hope for your getting on in the real world, and yes if you avoid these realisations, then you will inevitably be branded a racist and a bigot, because those are the views of racists and bigots.
