Why can't they?
It amused me when the news poll said the cons is greater than the pros. Not their fault though. Not everyone live in the same neighborhood. The environment around makes them think their way. I won't waste time for this. Do you want to be dictated by other people? Will you follow the voices that you don't even know? Dude, it's YOUR life. YOURS. Shouldn't we respect others?
I've heard lots of people doesn't want an LGBT near them (in the neighborhood for example). Why? It's their right to live. It's their money used to buy the house, not yours. So why you're the one getting hysteric? YOU could just move away if you don't like, voluntarily. They're human. They know they're different already without you pointing it out again. Some may not look like it, but you'll never know who're in the LGBT circle and who're not.
We have the right to say no to decline their (LGBTs) offers if they happen to invite you. To be cautious, not to discriminate.
Do you know how people feels when rejected? You might get rejected over 100 confessions of your love. Imagine that feeling, and multiplies by the number of people who harshly rejects LGBT.
