Vegans: Why is do people get mad when I tell them the truth?

[Benjamin]

So I have a little problem. I am a very strict vegan, I am a vegan for animal rights. When people ask me why I am a vegan, I tell them why. Then they get mad at me. WTF! I am usually a low profile person, but when I am on Facebook, if I see something that I think is worth sharing, I will share it. But here is the catch. I get billions of complaints. My facebook friends say "How could you share such an awful thing!" "Gross, delete it!" "Animals are tools!" "I am embarrassed to be your friend!" and crap like that. That doesn't bug me. But what does bug me is that all my friends post stuff about eating meat, their favorite recipes, and how they killed a deer for meat. So they like telling me their beliefs, but they don't like hearing mine? Well that's crap. Tell me what you think and what I should do! Thanks!
Deer Hunter- Thanks for the correction. Yes I do give my opinion. But what I mean by the truth, is how animals are treated. I share quotes, pictures of how happy animals are, and pictures of animals in slaughter houses and the horrors of it. So by the truth I mean how animals are treated! I hope that clarifies everything!
