@Jasper10,
I repeat once again.
Nature utilises electromagnetic + and - charge interactions.
It could be said that a + charge (= or balances) a - charge because they are the same.
However, we know that a + charge is not the same as a - charge because we get different results when we bring + and - charges together in their 4 off possible combinations i.e. -/-;-/+;+/-;+/+.
2 off combinations attract and 2 off combinations repel.+ and - charges are NOT (= or balanced or the same) therefore or all the combinations test results would be the same.
So as far as nature is concerned a + is not - and - is not +
