Same issue in my family, Elmore.

My little family-of-origin is surrounded by a sea of conservative to reactionary right-wing aunts, uncles and cousins. For us, it is not a question of not being allowed, it is awareness of the futility, and our own decision to refuse to engage in futile arguments with the true right wingers. We love them and they love us. We all have a strong sense of family obligation, and my most right wing uncle is also absolutely awesome at showing up when family needs some one to show up - and he ain't looking for glory. Just doing what he believes is his obligation for family and also for love of my mother.
