'Toxic people' used in reference to anyone who criticizes you. Nine times out of ten, there are no 'toxic people' to cut out of your life. You're just being an obnoxious, navel-gazing, inconsiderate shit. Instead of taking responsibility for being such a cunt, you've decided that everyone who has an issue with your behavior is 'toxic', and that if you cut them out you'll feel so much better. That is, until you fall in with a new group of people, and, surprise surprise, they all end up thinking that you're an asshole too. Wow, these toxic people really are everywhere.
