Does political correctness hold its ground?

As I see it, political correctness is a misnomer.
In a magnet opposing poles get polarized.
If there are only two parties, the polarisation is pretty obvious.
The smaller parties like a magnet with less influence would exert its power when positioned well outside the bigger parties.
Very often like a small magnet that get pulled into the bigger magnet, the smaller party get sucked into the bigger party ending its intended role.
What politics does is polarisation of an idea without a the set of tools to utilize the political wisdom to benefit the polity the idea (not the policies) was originally intended for.
It ultimately metamorphasizes to a family brand of buscuits for a single family to enjoy.
The best example is seen in Ceylon.
