What happened to good old-fashioned debate.

The ugly truth is, you don't have much to contribute to most conversations. Few strangers, if any, would be enriched by a debate with you on any subject. Biologists don't need to know what you think about evolution, physicists don't need to know your opinion of the many-worlds interpretation, and feminists don't need to know your feelings on street harassment. No one is missing out on any enlightenment by choosing not to engage with you. As you secretly suspect, you don't really bring much to the discussion table, and it doesn't take long for most non-ignorant people to figure that out.
