The result is that "voter suppression" is no longer understood to be a bad thing. You lose the ability to drop this phrase and expect people to pick up that the implication is negative. For example, you said above:
> Democracy is not 2 parties doing voter suppression and gerrymandering as a filter to pass the result to an electoral college.
If "voter suppression" as a term now include things that are universally understood as good, like banning toddlers from voting, this sounds incoherent. Democracy very much is about doing voter suppression, and everybody agrees it to be a good thing!
If you don't like how it sounds, you need to stop including good and proper things under the "voter suppression" label. Rayiner tried to help you with that, by distinguishing between mendacious voter suppression, and good and proper setting of voter qualifications, but you rejected that.
