I expect the comment was about your (pre-edit) "there doing" vs the current "they're doing", shame you didn't acknowledge your mistake in the change.
(I'm also not clear on what would make a typo ironic in this case.)
"Shooting down ideas is not a skill"
"This doesn't mean they know what they're doing. Their thoughts can be bad."What’s ironic here?
For the record, I was curious about what else you have written, so I read some of your posts and comments. And, you seem to be a very thoughtful and intelligent person. I'm sorry if my comment was offensive, I meant it to be funny.
