AIO if I blocked my friend over a misunderstanding?

Context, my friend thought I supported Trump because she saw I followed him on Instagram, which I literally don't remember ever doing but I checked and I was? She kicked me out of the gc and unfollowed me and was going to just do it silently but only texted back after our other gc members were questioning her about it.

Her apologies don't really feel genuine and it almost looks like she kept trying to justify herself? I was really upset about it since she is one of my best friends, but now I want to just block her. Would I be overreacting if I did because she already said sorry?
