Question: Can you delete threads that have been closed or is that not possible

I'm just asking because like ya know i posted something earlier today relating to how i was feeling about something and it got closed which i understand the reasons why but i feel bad for posting it and was wondering if there was a way to delete the post or anything.

It was about people speaking up for other communities of ethnicities and religions (these didnt happen on here btw only on like relic castle and reddit) as a serious off-topic thing cause i didn't know where else to like vent to in a way.

But yeah I was just asking so that it doesn't happen again really.

That's not a problem, I'll go ahead and remove that now for you.

Thank you!! I felt bad for going on about it honestly so i just like would appreciate that so much!!
