Why do Liberals show urgency for LGBT persecution/genocide but are apathetic to the Gaza genocide/willing to sacrifice lives there?

This is something I don't understand. One major issue that liberals stressed was that people needed to vote for the dems in order to stop LGBT persecution or genocide under a Trump regime

So caring/wanting to stop that is on the right side but something I don't understand is that these same liberals saw an ongoing genocide and went "tough luck" or "they're already under the bus"

I can't understand this. If two groups are facing genocide, why were libs so ready to throw Gazans under the bus or sacrifice themselves or go "oh well" instead of creating a sense of solidarity or empathy?
