Muslims are pretending that aicha's age was 19 on social media

I keep getting random posts on social media about muslims mocking ex muslims for the pedophilia allegations, apparently we're just ignorant and brainwashed and that's probably why we left the religion that we probably grew up with from birth. They're starting a new lie which is that aicha's real age was 19. I have never heard of this until lately . In my country we have this subject called islamic education that we study for 12 YEARS and all the religious teachers that i had agreed that aicha's age was between 8 and 12.
