I'm not sure, is anti-electorism, as an idea, something that needs explicit protection? I can empathise if someone is staunch anti-electoralist and it's election season again - it probably leads to a lot of unpleasant conversations everywhere. However I don't think it's worth controlling someone's free expression. People are going to be passionate on the internet. Shaming is a legitimate social tool, it's upto you reject it.

While defending anti-electoralism might be a tough job, I think the idea needs to be defended on its own merit instead of a thumb on the scale. I don't think anti-electorism as an idea is at par with other ideas (e.g. anti-capitalism) that require explicit, instance-wide protection.
