I have an unpopular opinion about things said during an argument. As an adult, anger is not an excuse to say hurtful things you cannot take back.
If you really respect someone, you will mind what you say even when angry.

See, as a teen still finding emotional maturity, it might be fine. But at some point, anger can no longer control you. There are many options.

1. Ignore
2. Walk away
3. Ask to table it for later

I take how someone relates with me when angry seriously. I don’t excuse it
