If I understand correctly, although the GP may have been suggesting government subsidy as a possible solution, the point wasn't that this is somehow "best" from broad or moral reasons.

Addressing that issue is compatible with concurrent solutions that outlaw the discrimination on moral grounds, or do so more strictly, or provide more aggressive enforcement.
