The whole "we need to support conservative artists!" thing is thinking past the (bad) sale. The right answer is "we need to support an arts community that is open to people who don't parrot a party line." Because most artists aren't conservative or liberal, they're weird hodgepodges of confusion and chaos and crazy and experimentation and changing beliefs. They're our reminder that we can grow and shed our skins and feel no shame about learning, evolving, and changing our minds.
By definition, they're not clean and predictable. If they are, something's gone wrong.
The only reason "all artists are liberals" right now is because you need to be one for access to most distribution infrastructure. If all the tastemakers and patrons and publishers and gatekeepers require you to profess their belief system, you either become a grumpy, scarred, lone wolf doing her own thing (like me) and accept the suppression of your career, or you adopt the beliefs of those who will help you, either cynically or wholeheartedly, whichever you can live with.
But any conservative who says they want more conservative artists is gatekeeping again. They want artists to be obedient and fit in their square holes, not the round ones. That creates the same mistake, from the opposite side. That's a call for propagandists, not artists.
I'm an artist. I should both delight and offend everyone by turns, or I'm not being honest with myself.
