This is so true. I have a working theory about this phenomenon: it's essentially a slow radicalization. The algorithms present content that keeps you engaged, often placing you in a slightly hostile environment, opinion-wise. As you try to resist and stand your ground, you slowly begin to drift in the opposite direction. You're compelled to form opinions on topics you didn't previously care about, and you shape these opinions in opposition to the subtly hostile environment. They support unisex bathrooms, you are against it. They support Ukraine, you support Russia. They say that they hate nazis, you become antisemite and Holocaust denier... It is a dangerous slippery slope.
