The right is good at presenting false binary choices as a way to delegitmize opposing viewpoints:
On health care:
"Free enterprise" vs "Government takeover"
On fiscal policy:
"Fiscally responsible Republicans" vs "Tax and spend Democrats"
On immigration:
"Enforcement" vs "Open borders"
These are always presented as the only two possible positions. But life is full of nuance, and everyday living always presents you with more than two paths to solve any problem.
This is hardly unique to the right. They just happen to be the masters of the tactic. It happens on the left as well.
