conservative - that's about not liking change for its own sake.

radical - that's about when your are cahnging somethingt, doing it thoroughly, getting diown tio the root of the troubls.

liberal - that's about trying to see the other person's point of view and not pushing them around.

All these words are about very different characteristics, which are in no way incompatible with each other. There is nio reason someone can't be a liberal, radical and conservative at the same time. With lower case initial letters of course.

Setting them up as if they were opposites is to oversimplify and distort, and its done by politicians and others as a way of manipulating people, and stoppingf them thinkiong clearly.

The idea being to get a response "I don't like this, so it must mean I like that; and I do like this, and that man says he likes it too, so I must like him." Put like that it's transparently silly - but most of us fall for it time and time again.
