I’m a fan of both, and significantly more of a Star Wars fan if I’m to be honest…

…definitely the Star Trek shirt, the Star Wars fandom can’t even agree on which trilogies are good or bad (and this subject often leads to vicious arguments), and I have seen some really vile political trolls insinuate themselves into the fanbase.

Meanwhile most Star Trek arguments I’ve had online tend to end with someone presenting proof and everyone agreeing on it, or saying things like “I don’t agree, but that’s a fair point” in the rare case it can’t be resolved.
