Look, if you insist on using this term like this, it will make conversation and mutual understanding more difficult. If banning toddlers from voting is "voter suppression", then now we must distinguish between "good voter suppression", like banning votes from toddlers, and "bad voter suppression", like for example tactics to mendaciously make it harder to vote for people who are otherwise eligible.
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.
