It is a bad thing, because the law protects our disagreement with the election deniers/MAGA diehards only as much as it protects their disagreement with ours. Having the same opinions as people who did illegal things isn't and shouldn't be grounds for targeted surveillance.
The pendulum will swing the other way eventually, and they'll be digging into the messages of people that talk about defunding the police because "antifa" took control over part of Portland for a while. Or target abortion activists because they caught a few people trying to assassinate Supreme Court justices.
Trusting that government overreach will only affect the other side usually backfires.
