It absolutely is, but don't expect it to actually change anything.
The usual avenues to air grievances that modern Americans are used to, like writing your representative or even peaceful mass protests, only work in a political culture where they are universally perceived as detrimental to government's legitimacy and that matters. We are past this point now, and, arguably, have been for a while.
For an example of how well such tactics work in a different culture, look at e.g. https://en.wikipedia.org/wiki/2011%E2%80%932013_Russian_prot...
To put it bluntly, Trump and people who elected him don't give a fuck about "whiny libs". If you want to convince them to change course, you need to cause them actual measurable harm. Starting with economic - mass strikes etc - but be prepared that government would escalate to physical and match in kind.
