Can anyone think of a way to ask for reasons why Trump should be impeached but by asking for it in a more politically correct and on topic sort of manner on SE Politics?
If that is too broad entirely to ever work here then how could someone ask a question to get back such answers but by asking it in a different and not so blunt way where it would not be closed?
The problem with asking for reasons why Trump should be impeached is that it is completely opinion-based. And I do not mean opinion-based for us. It is opinion-based for the congresspeople who make the decision to impeach or not impeach. The US constitution says that a president can be impeached for "high crimes and misdemeanors" and whatever that means is open to the interpretation of congress. Fact is, impeaching the president is a political decision, not a legal or ethical decision.
And besides, this would be a list-based question, and these don't really work in the Stack Exchange system.
If you just want to collect a "list of things Trump did wrong" which you can then use to agitate against him, then you might want to look for a more discussion-oriented platform with a declared anti-Trump / pro-Democrat agenda.
As I've stated before on other questions related to opinion, I believe that a question that can be responded to with fact or research based information is perfectly within the scope of the community.
Can a sitting US President be impeached for perjury?
This question can be answered with a fact based response, doesn't mention any particular person, and has a broader context than asking about a particular incident related to perjury.
One potential correction is to ask about what has happened instead of what might happen.
Try:
What reasons have U.S. congress-people mentioned for impeaching or not impeaching President Trump?
This is a straight-forward empirical question. It can be answered based on the public statements of a narrow set of governmental officials. It doesn't directly answer your question of why the President should be impeached, but we don't answer normative questions like that here.
I'd say it's impossible before a trial happened and we know the outcome. Any answer would rely on assumptions (if X happened then) or speculation (we can guess that X happened because ...).
If it were a simple case and the evidence were there then the impeachment process would already have started or the evidence supporting the process would have been put in the public domain (e.g. those with the evidence cannot start an impeachment procedure so they make it public to rally behind their cause).
