Telling someone that their thought process is flawed/immature is not the same as being triggered. The amount of text contained in your answer is usually associated with “being triggered” though (at least in my experience)

Then again, depending on what exactly one means with “triggered”, you could say that you’ve “been triggered” (like activating some mechanism or something) to write a long response :D
