Everything is an argument.
I, personally, do not come to this forum or any forum to have 'conversation'. None of you are my friends and I don't particularly care about any of your opinions/tastes/preferences.
I come here, specifically, for TTRPG news and to argue, analyze, and debate concepts and occasionally to get feedback on ideas or to find the answer to a question. Anytime someone puts forth a statement that does not express a matter of taste, they are making an argument - usually they're saying that something is true.
Maybe some people just want to have a space where they can say "I believe that X is true" but don't want to have to justify or explain their position. Fine, whatever; I don't really understand the point of just shouting words into the void, but some people seem to like to do it. I'm actually doing that right now, but this thread explicitly was asking for people's opinions/tastes/preferences, so I don't feel too bad about it.
