It is likely that a lot of them are Libertarians rather than being homosexuals or having a homosexual relative.
Libertarians are for freedom, but some things that people do are destructive to themselves and society, and intolerable, which I find a naked “Gay” pride parade to be, for example.
My late brother was homosexual, but there is no way on God’s Green Earth that I would ever be in favor of calling that behavior “marriage.” Nor am I for homosexual people adopting children.
Lord Jesus in Heaven is watching the behavior of humanity toward His precious children. There is a special place in Hell for those who defile the children.
A few of them have been homosexual, but I agree with you that most of them are probably Libertarians, although some have been liberals, who appear to come here to straighten us all out.
I was a libertarian for a few years. I even attended some libertarian gatherings. I thought libertarianism was about limited government and personal freedon. Imagine my surprise when I discovered that for most of the libertarians that I met it meant one thing and only one thing: legalizing drugs. Today I gather it means two things: 1.legalizing drugs and 2.making gay okay every day in every way, but I long ago recognized it for the anarchy that it is and fled back to sensible conservatism.
