𝐊𝐚𝐥𝐭𝐰𝐞𝐢𝐬 @kaltweis.bsky.social · 04/10/2026It seems that only a sentiment shift may get rid of #resentment, not argument.

𝐊𝐚𝐥𝐭𝐰𝐞𝐢𝐬 @kaltweis.bsky.social · 04/10/2026Also: Those who hold such views are most likely not able to follow the logical structure of an argument, but rather act on the #resentment they harbor.
