Why do our screens freeze and we can't use our mouse after we post something non-threatening but honest about Biden and his administration.?

That's an issue with your device and/or internet connection and is not related to the topic you are posting about at all.
.
Your question belongs in Computers & Internet as it's currently in Yahoo Products>Yahoo Answers and not applicable to this subcategory, which is for questions about how YA works and the rules here (and thus decreases your chances of getting many useful answers).
Moving your question can be done by clicking Edit (pencil icon for mobile)>Edit category just beneath your question, then selecting the category that's appropriate for the topic.

Your device has to be in desktop mode. What the question is about is totally irrelevant. The server computers?and computer programs don't care what your question is?about. There are NO Yahoo or Verizon employees reading your questions before or after they post. 

The problem would be your device. If on a mobile, get in desktop mode. On a desktop, do a good cache clean. The topic has nothing to do with it.

Hmmm...I haven't noticed any sort of occurrence, and I have had occasion to criticize both Biden and Harris in these hallowed confines.

It must only happen to Trumptards like you.
