You said that; the 25th is part of the Constitution which implies quite directly that you don't take the Constitution seriously, I didn't interpret anything, words have meaning and you said directly that you don't take part of the Constitution seriously.

Nixon resigned on the threat of being impeached, so please lets not pretend the threat alone isn't enough to cause action. Trump could very well resign to avoid the embarrassment of even having charges brought. His ego is quite easily injured. Just because you think they need a solid indefensible case to even attempt charges doesn't mean that's what everyone thinks and quite simply isn't how the world works. You live in a country where plea deals are taken every single day to avoid the risk of even going to court; quite often in cases where the DA knows they don't even have a good case.
The only thing preventing Trump from being impeached is that it's his party in control; that's it. There's plenty to impeach him with that will hold up in court and you're simply incorrect to say otherwise.
