They're wanting to force upon others their vision of "social justice" through political activism, not the freedom of speech, and legislative fiat without the consent of those others!

BFD.
That's what anybody who advocates for or against any legislation or policy is doing. And yes, our freedom to do so is God given and Constitutionally protected.
If you can't handle that ... if you can't handle people who disagree with you exercising their freedom of speech ...
You might find North Korea more to your liking.
Some cynically minded people need to get their heads out of their asses.
