The catch TTT is that, by definition of the rules you are trying to insist Trump has already won under, he actually hasn't won at all yet. Because this -- the Electoral College -- is what matters, as you are so fond of reminding people who complain about how Clinton won the popular vote rather convincingly. So either you accept the current rules (in which case, asking the electoral college members to consider whether or not they should stick to their guided result is part of those rules), or you don't -- in which case, why *shouldn't* the electors reconsider, given that the popular vote went against Trump?
None of this is to say that the Electoral College should reject Trump, and on that basis I'm not sure that it achieves anything other than to look bad to appeal so strongly to them to do so. But it is hardly "anti-democracy" -- or, at least, no more anti-democracy than the existence of the system in the first place, that conspired to reject the overall will of the American people in favour of the American *states*.
