Am I being a bigot for thinking that the lgbt rainbow symbol is a perversion of the Abrahamic faith ?

[Kurobecky]

I don’t hate gays or transgenders, but I feel like there’s a very anti-Christianity/traditional Islam in the lgbt community lately. I remember that my father taught me that the rainbow was a very holy and sacred symbol and a lot of the biblical stories he told me featured one. I believe that it’s associated with both the Noah’s Ark and the archangel Michael. Is it just me ?
