It's much better to say "I'm afraid for the safety and lack of equality and freedom for gay people if being gay is illegal." By focusing on Muslims, you're making it personal and ignoring many non-Muslim countries and religions which have anti-gay beliefs.

If the gay equality issue is important to you, why are you focused so narrowly on Muslims? Why not simply focus on your core issue which is equality for gays?

Making it about your fear allows people to hear you and is not arguable. Saying "Muslims are anti-gay" is arguable because you can't accurately survey billions of Muslims worldwide and statistically you'll probably find millions of Muslims who don't agree with every aspect of the religion and some that are gay themselves.

Religion and races are not consistent or homogenous. Lumping people together on those criteria is rarely accurate or productive.

For semantics, the term racism applies to race as you mentioned. If you hate Muslims that I suppose the best way to describe you is bigoted or a religious discriminator.

And as you seem intent on the pizza aspect, pizza isn't a person. While hating a pizza sounds like anger issues, it's certainly not the same connotation or implications of hating a person. If you want to be kinder to your pizza friends, you could say "I prefer the taste of thin crust pizza". If you want to be kinder to your human friends, I would focus on what you want rather than what you think a group of unique people is all acting out in unison.
