Agreed, even the title seemed like a dog whistle to me.

Their subsequent bashing of The Progressive Activist confirmed it.

Then when they compared discrimination based on political views (which you pick) with discrimination on race (which you don't get to pick), I wasn't even surprised.

Who the hell are these "Ethical Systems", and why the hell should anyone listen to them?

(I guess we could believe them because an unethical person would never call their org Ethical Systems /s)
