About treating well, I'm okay with that. about support though, it will be over my dead body. I won't support something that I see abnormal and literally a sin in my religion, sorry but I won't put your gay feelings in front of my religion and beliefs. we all are humans sure and I'm okay to deal with gay people but I'm not okay to get shut by them when I use my right to reject supporting them, I'm against them shoving their gayness into my home and make my kids think it's normal. same like someone who drinks a lot, sure drinking is sin too and sure I will never support it but it's not like I won't deal with the drinker (maybe we won't be close friends but maybe work fellas) 
I have problem with their act and I have problem with being homosexual. I'm not having issues with someone in specific and as long as I do not insult someone in specific then it's my right to say no to it.
