You could (and should) have made this point without the personal attacks. Something like "if you're blaming immigrants for this, you are greatly mistaken".

Why pussy foot around hurting the feeling of ignorant gullible racist xenophobic sacks of shit who blame powerless immigrants instead of powerful oligarchs for their economic and unemployment problems? I thought MAGA cult members loved it when people say what they're really thinking no matter whose feelings get hurt, instead of being so politically correct. Who's the sensitive snowflake now?
