I believe it is how you are raised on how you react to that news. I was brought up in a very conservative house that was anti gay, anti trans, anti minority, etc. (not all conservatives are like that, just giving my personal experience) When I got older I decided that wasn’t right and went my own way. I respect my dad, but not his views on people different than him. I would definitely be his biggest supporter if he was a CD because my other siblings got brain washed into that mentality and I escaped it.
But we were all raised different in that generation and previous generations. The younger generation is far more supportive of things like that. millenials are raising their kids to be far more accepting. The most unique generation by far.
