It seems like the pendulum is just swinging more and more wildly, creating more and more extreme ends, but maybe it's just the media blowing it up to be bigger than it is. I align pretty well with conservative views, but if I label myself as a conservative, I risk also being slotted into the generalized "Trump-loving, homophobic racist" group, hence why I hesitate to label myself really clearly when asked.
I'm pretty sure this is the case with most people and there's a lot more complexity to their beliefs than we might be led to believe on both sides. I suspect we just see the dramatic vocal extremists on both sides and others that are more centrist or nuanced in their positions don't get the limelight because frankly, they probably don't want it.
