Acting like common slang is somehow incongruous with "philosophical" conversation and voicing that opinion is hilariously hypocritical. I urge you to consider what it is about that language that upsets you so much and take some time to work on it. I use common slang mostly because the point is obvious and using big words makes people feel like the speaker thinks they are above everyone they are speaking to. I wrote out that entire long ass sentence instead of saying you sound like a conceited jackass because I know you edge from unnecessarily long phrases.
