I'm 51. My evidence that conservatives are inbred is Alabama.
I didn't ask you or care how old you are. Peabody made an asinine statement about conservatives, I thought maybe he/she was a child. Your "evidence" is Alabama is pure bigotry and just as asinine also.
You asked about evidence that conservatives are inbred. A heavy majority of people from Alabama voted for the Republican party in 2016. And it is legal in Alabama to marry and/or cohabit with your first cousin in Alabama.
Ergo, evidence, as you requested.
Not all conservatives are inbred, but it is certainly likely that some of them from Alabama are.
