In Matthew yes. In Mark He makes no such distinction.
How would the daycare known if they'd been divorced and remarried?
Ask?
Secondly, homosexuality/sexual immorality is not to be condoned.
Nor is adultery I would think.
You mean Mark made no such distinction. Matthew did. We are talking about 2 eyewitness accounts that each record what they remembered. Combining eyewitness testimony gives a fuller picture of events whether it's police work or even the Bible.
The Bible condemns any sexual immorality.
