That's because you've posted controversial religion/politics questions in the past. Don't worry about it. Those kinds of questions bring out another side of people. Occasionally, I get it too. But it's just the internet. It's not like these people really know you. So try not to let it get to you.
They do the same thing to me almost every time I mention Jesus or anything about the Bible. They call me a child, call Jesus a fairy tale, the Bible a fictional book, Heaven as the world's biggest bath house and they call me and Jesus gay when I say "I love Jesus and He loves me." Not on here, but almost everywhere on the Internet. I hate it!!!
I personally am having similar problems, pay no attention to them. Stand up for what you believe even if it means people hate you. I've learned the more others hate you, the more others will like you too.
