Filtering is a cowardly choice–most of the time. But sometimes it serves a purpose. For example, when someone is posting endless tranny hentai or faggots eating shit or splattered dead people, I'm gonna filter that shit. When EBot is making 60 posts per bread, I'm gonna filter that shit. When Tiresias is being a moron shitting the bread, I'm gonna filter that shit. None of them are part of the conversation.
But filtering because you don't like someone's words? That's for libtard pussies.
