Respect has something to do with recognising integrity. Armchair generals and armchair revolutionaries deserve less respect from people who disagree with than people who risk their lives what they believe in.

I think you can respect qualities in people even when overall you despise what they do and what they stand for.

That surely applies in political and related matters, and in music and literature and so forth.

I think it's quite possible to respect and admire the musicianship of people even when you loathe what they use it for, and the personal qualities which are reflected in that choice on their part.
