The traditional way this was phrased was “bleeding heart liberal”. The implication being that they were so giving as to be gullible and not realistic.

Nowadays the preferred insults are “commie” or “woke”. I don’t hear it directed at me much, due to particular family circumstances that forced them to accept my gay-married trans ass, but boy do I hear it about Democrats every year.

(I know that Dems aren’t commie or even ‘woke’ most of the time, but to them it is a distinction without a difference. To them, those terms refer to anyone who thinks that people don’t deserve to die for the ‘crime’ of being homeless.)
