Some are, but this is kind of like saying "all Americans are entitled narcissists" or "all Australians are assholes" or "all Mexicans are lazy" or any other generalization. There are tons of Christians who don't try to force their beliefs on anyone and don't care what you believe and just quietly believe in the religion. Unfortunately the ones who are assholes are the ones that draw your attention. My mom is very religious, her whole life is dedicated to her church, especially after all her kids grew up. But she does only good things for her community and everyone she meets. She believes that Jesus commanded us to love everyone, and she has been instrumental in transforming her church into fully accepting gays (the current pastor is gay), housing refugees, feeding the homeless, and fights actively to be there for people in need. She believes in radical love and acceptance and that Jesus taught the same. It's a shame the shitty Christians (who would be shitty people if they were some other religion too, or if they were atheist, they're just looking for an excuse to take their shit out on other people) have tarnished the entire religion because, although I don't think we need organized religion and it tends to lead to conflict in the world, I think it only does this because it's a convenient tool for leaders to mobilize people against other people. At its core, when people are actually living the way that Jesus taught to live, it can be beautiful. I have attended a number of churches regularly as an adult, mostly because my ex was a church pianist, and 2 out of 3 of them were full of lovely people and I enjoyed going every week because it was nice to see a group of people really giving back to their community and making it a better place, and I felt the love being among them. I grew up going to church every week too, and most Christians I've ever personally known are perfectly fine people.
Intolerance against all people of a religion is itself bigotry. I have intolerance for arrogant judgmental asshole Christians, but love for the rest of them (as I have love for anyone who isn't hurting other people).
By the way in case there is any confusion, I am not religious at all.
