He was a sexist, accusing him of some inane bias isn't going to change the fact that the man was a sexist

Is there any source for this? I think the scientific consensus last year (at least in the US) was that big protests didn't turn out to be super spreader events

There isn’t. The protests were at their peak last year. If you look at the case growth, it begins in feb/March. Since case reporting tends to lags infection by 14 days, we know that they have nothing to do with the protests.

Sadly though, the protests continue even today, and I have not heard of any response from the govt.
