This is what the radical Lefties would call "direct action."
The conservatives who are (rightly) outraged at the gay wedding cake issue and Indiana, etc. do not want to draw the direct link --which liberals tout-- between anti-discrimination against Blacks, which all decent conservatives support, and any anti-discrimination law whatsoever, for any damn reason the State wants. There's a long straight line from the hallowed Civil Rights Act of 1964 to forcing Christian businesses to serve events that they reject on religious grounds. If you wanna praise one, you're gonna wind up with 'tother.
The problem is way deeper than vicious queens.
