I think it's barely worth protesting now (in the style it's mostly being done), because of how ineffectual that will be in obtaining results.It certainly appears that the protests today had some effect. It at least increased awareness. Don't dismiss protests with specific purposes out of hand. The MLK Jr and others of the Civil Rights Movement were very effective when doing just that. And there are those on HN today that participated.
In terms of money, I've read numerous comments where members have made donations to the ACLU and other organizations.
I agree with you that there should have been more done to roll back the infringements on civil liberties that go back all the way to at least the Patriot Act. There were people that did, even though it was very difficult to do so without being cast as unpatriotic. I don't see how it does anyone any good to say "Well, you missed your chance then! Just wait until you get a president you like, you can protest then!"
As for "fawning over a liberal president", have you noticed the contortions some are bending themselves into reconciling the many blatant mistruths and inconsistencies uttered by Trump during the campaign? For goodness' sake. Not everyone on either side fits in either category, but there are those who do. Focusing on that and using such pejorative language does nothing to help the situation.
Certainly people should remain critical of even the politicians they vote for. With a limited number of parties, it's unlikely that any one candidate is going to align perfectly with anyone's particular set of values. But to admonish people to stop now because they weren't adequately righteous in the past is just asinine.
And there are those of us who aren't really happy put in one party or the other, but have issues we care strongly about. Do we get categorized as a Democrat when we happen to align with them and a Republican on other issues? What are we supposed to do, regardless of which party the President aligns with, or which party holds a majority in which chamber of Congress? Let people work together on the issues they care about, regardless of party affiliation.
Unless you have another agenda.
I ask you again: Do you support the Executive Order?
