I personally don't approach them at all. I'm speaking of things I read on Facebook and everywhere else on the internet.
Homosexuals and their supporters are, bar none, the most hateful people I have ever had the misfortune of hearing from.
I'm currently reading all over the Internet about a 21-year-old white man who killed 9 blacks at a church. That doesn't make all 21-year-old white men killers.
A white police officer was recently charged with murder for shooting a fleeing black man in the back several times. The video of that event will probably put him on death row. But that doesn't mean all white police officers are hateful racists.
In 2011, a Christian pastor burned a copy of the Koran (the Muslim Bible) in a stunt that he knew could cause violence against Americans overseas. As expected, the result was violent protests and deaths in Afghanistan. But that doesn't mean all Christians hate Muslims.
In other words, I wouldn't equate openly angry LGBT people with all LGBTs. Nevertheless, I fully understand their anger. They are human beings (including many Christians) struggling to overcome discrimination no different than that faced by blacks. The same Bible currently used to justify homophobia was once used to justify racism.
In many parts of the country, LGBT are hated; threatened; killed; at risk of losing their jobs, health insurance, and homes; are prevented from being with a dying partner in a hospital because they're not "family"; are prevented from adopting children in need of loving homes; and are often discarded by their "Christian" families, leaving many teens (kids!) homeless. Up to 40% of homeless teens are LGBT.
I would recommend you read the following article:
https://en.wikipedia.org/wiki/Matthew_Shepard
It's about a young gay man who was tortured and left to die in a horrendous way. It is one of the most heartbreaking killings of a gay man in my lifetime. His death was as awful as that of Christ, except it took longer. I don't cry often, but I did for him. I still do.
ISIS/ISIL terrorists in the Middle East have found an equally creative solution: throw them off tall buildings and, if they survive, stone them to death.
Personally, I would be happy to allow Christian businesses to refuse to serve LGBTs on the basis of religion. But I don't know how to reconcile that with the right all of Americans to be treated equally. How is a sign that says "no gays" any different from one that says "no blacks". At a minimum, shouldn't the sign then also exclude all adulterers, all blasphemers, all those who disrespect their parents, who bear false witness, work on the Sabbath, or any of the other nearly 1000 sins listed in the Bible?
And if we're going to continue to discriminate against LGBTs based on what it says in the Bible, then shouldn't we also debate stoning sinners to death, as advocated throughout the Old Testament. Why does that never come up?
