You mean when the leftist controlled FBI put them on a watch list for voicing their concern over masking up for an illness that had a 98% recovery rate . . . oh and also made sure that social media platforms censored them? That sort of 'permissible' protesting?
Now if we want to talk of permitting protesting to the limits of no matter what, we hark back to the leftist summer of love of 2020 when for nine months ANTIFA and BLM 'protestors' freely rioted, looted, and burned to their heart's content while leftist governors and mayors STOOD DOWN the police.
