Sometimes the mods let someone make an account even if they aren't really very principled in the hopes that they learn and get educated. Sometimes it does work, but sometimes we have to tell them that their lib bullshit isn't acceptable here.
Someone willing to make an account to listen and learn is probably doing fine. I don't think it is a bad policy, I think this is the first time I've seen unrepentant lib behaviour from a lemmygrad account, so this is an exception, not the norm.
