I’m really not trying to dunk on you when I say this: you’ve fundamentally misunderstood the left-right political theory. A previously left-wing party can drift to the right and vice versa. A party called the “lefty left socialist communist hippy party” can be made up completely of right-wingers, and that doesn’t change the definition of left and right. I won’t try and explain the definitions of political left and right to you because there are almost definitely better explanations out there than I could give. I just implore you to find an impartial, unbiased explainer.
