Did Parler have 74 million users planning murder? No, this isn't delegitimizing conservatives. It's delegitimizing people who are insane, and in this case many of these insane people happen to be conservative.
The message I was replying to (apparently deleted) implied that everyone who voted for Trump is in the same wagon, and Parler is illegitimate simply because it was funded by Trump voters.
Do you really think it's a viable strategy to try to de-legitimize them all?
