It may not do much depending on the mods/admins, but it never hurts to report and downvote comments or posts like that.

Emphasis on reporting there, as I think sometimes that stuff lingers around because people have made a habit of only downvoting and blocking those doing that regularly. I realize in your examples it’s more likely bias or bigotry respectively, but still.

Report first, then downvote and block. Doing only the latter only makes your experience a little better, the former may help the community.
