I guess I'm not following you Kimba. That, or we're talking about 2 different things, unless you can find some examples of conservative minded folks pushing the idea that liberals and/or Democrats should just shut up....that they shouldn't be listened to.
The closest thing I could reference is when certain anti-abortion folks will paintbrush those who support abortion as baby killers. Now, that's an accurate conclusion, though its both overtly emotional, and paint brushes everyone who's not anti-abortion, as supposedly advocating the killing of an unborn child. That's a little unfair, and over the top, since I'm sure some folks just want to advocate the freedom of the woman to do whatever she wants. Now, I'd even support that....if it didn't involve the life of an innocent unborn child, that has no say in the matter. Point being, that's rhetoric used to try and shame folks into either changing their position or simply not voicing their opposition.
But as I said, the folks that demonstrate the greatest amount of intolerance to opposiong POV is the same group that brands themselves as being the "tolerant" ones....that being liberal progressives......bordering as fascists
