I'm becoming vegan...but wow, I didn't realize that vegans were hated so much

I've been flexitarian most of my adult life but have always wanted to become a complete vegetarian. In the last several months I've learned awful things about the egg and dairy industries and have made the decision to be vegan. I've started following vegan pages on Facebook and omg, the trolling from meat eaters on those pages is insane. It's happening on pretty much every page I've followed. I don't understand it. I've always admired vegans for their dedication. I'm just blown away by the hatred. I don't understand it. Vegans aren't hurting anyone. Why are people like this? Is this what I will be facing as a vegan? How do you deal with the hate? Also my Facebook friends have been mostly ignoring my vegan posts and has me a little sad.
