I don't even know what this post means. "Take to the streets"? The fuck is that? I'm sure you can find anti-Trump protests all over the place, just like you could find anti-Obama protests. Who gives a damn, it's not going to do anything.
I'm not sure what you mean about Europe so you'll have to give more details about how protesters could remove a head of state from office. How does that process work?
As far as Trump being removed, that's a matter of law. If he does anything that constitutes grounds for impeachment then he can be removed. Otherwise, he will remain President until his term is over. There is nothing confusing about that.
He's done PLENTY that should be grounds for impeachment:
-Allegations of sexual assault.
-Conspiring with a foreign entity.
-Escalating racial and classical tensions.
-Made foreign relations with the United States much worse.
-Taken away net neutrality.
