Which is ironic because the progressive ideal is to leave the concept of "normal" behind entirely and embrace new different things instead of excluding those who are different.

if what’s normal changes, they’ll have to change to be normal. Or even worse, they’ll be excluded from the normal.

Based on how much time I spend voluntarily associating with any openly conservative family members or coworkers these days (none), my anecdotal evidence is that this is already happening.

They are bringing it on themselves, but there's really no point trying to tell them that.
