Rant. Also, how to people deal with homophobic idiots?

Trigger warning (Am I supposed to put one up?) Talking about nasty anti gay comments and also mentions pedophilia etc.)

This is kind of weird for me. I came to terms completely with the fact that I'm bisexual at the start of the year (Though I really should have clued on earlier). The past few months I've been accepting that I probably have a preference for women (I'm a cis female), but could still fall in love with the right guy.
Since I'm still figuring out things a bit, I haven't come out to very many people, only my 3 closest friends, and this one guy I've been getting close with (as friends). And I'll be telling my parents soon. But nobody else knows.

Anyway, usually I see anti gay/lbgt+ stuff on facebook, but it's usually a comment on an lgbt facebook page and they get squashed. Never anybody I know.
There's this guy who, until he left about a week ago, I worked with. We weren't overly close, but we got on. We aren't friends on facebook but I ended up looking on his profile (You know how it happens )
The first few statuses were about how they can't legalize same sex marriage in Australia. He then went on to say awful things about people who like the same sex, like that we're filth, or have sick sexual fetishes. Comparing it to beastiality, incest and pedophilia (As someone who knows people who were molested as children, that's just sick. Two consenting adults getting married cannot be compared at all to destroying an unwilling childs life!). Saying that same sex marriage just opens the doors to all of that. He uses his religion to justify it all. And even worse is people were supporting him, including some drug dealer/meth head that my ex used to work with, who actually seemed really nice despite his issues.

So that's two people I know that think I'm filth. Well they don't know it yet, but that's pretty much how they would see me.
I don't know, I've just never known anyone that says that kind of stuff. My parents are supportive, my half brother came out as gay probably 10 years ago now. Even when I thought I was straight, I always kept lgbt supportive people around me I guess.

Now I'm angry and upset. I'm angry that people think my brother and his boyfriend are filthy and wrong for being in love. I'm angry that me thinking the girl I met the other day is beautiful and lovely apparently means I have a sick sexual fetish.
And mostly I'm hurt. Because I haven't done anything, and my sexuality hurts nobody, yet I'm meant to be wrong and destroying the world because of it. Like I can help it. I'm hurt that somebody who I had an otherwise good work relationship with would think I'm disgusting. It makes me wonder how many other 'nice' people I know would think I'm disgusting.
I feel like a massive sook right now because all of you guys probably have to deal with this sort of crap from your families and close friends. I've just never encountered a real person who's so against love.

Any tips or advice on how to not let this kind of stuff affect me so much in the future? I feel like it's pushed me to a tipping point where I either want to crawl into the closest and never come out, or run out and scream it from the roof tops haha

Edit: How *do people deal with homophobic idiots

 

Thank you! I feel like I need that
