Sticks and stones may break my bones, and single words here and there won't hurt me, but en masse they normalize an attitude of supremacy and derision toward folks that super don't need any more. No snowflake thinks they caused the avalanche, but lots of us have to live with the consequences of this in daily life regardless. Shock value slurs are also just... tired and played out at this point. Whatever humor they had at one point doesn't really land in the same way anymore.
