Why do I have no longer have the ability to edit my question? Blocking the comments should not block my ability to edit the post, since I have been subjected to ridicule, particularly since I have very relevant, significant, sourced information to add to it.
You no longer have the ability to edit the question (read no one, barring mods, has the ability to edit your question for the time being) because it has been locked by the mods.
Yes, locking a post does lock all features of the post including commenting, editing, voting, and answering.
The reason given was off-topic comments, which seems entirely valid given there were 20-ish comments on the question, many of which were ad hominem and all sorts of nasty stuff.
This type of lock is temporary while the issue is being resolved on meta. Once the discrepancy is resolved the post will be unlocked and dealt with accordingly.
Just as a general note to all parties involved, please remember to be civil and respectful to others.
Rudeness will not be tolerated.
