I wish we had moderation policies that would just remove mantras like the above, which contribute precisely zero to the conversation. We all know what they are: "do you like [licking or some variant thereof] that boot [, bootlicker]?", "cry more, libtard", etc. They only serve as a thought-terminating cliché, to assert the speaker's own tribal allegiance and to place their interlocutor on the 'wrong side'.
I really don't think HN would be any the worse if they were removed. Anyone who wants to have a slanging match rather than an intelligent exchange of ideas can go to the Other Site.
