Yeah, the whole "England will send you to prison for posting an offensive meme!!!" the far-right Americans keep crying about is misleading and inaccurate. We have laws against malicious communications, causing fear and alarm, stalking and harassment etc but the threshold for charges is relatively high. If charges are issued by police for these crimes it's usually after a prolonged stalking campaign where someone's life was made hell or if they made a threat to kill someone or commit an act of terrorism, not because someone posted a meme or called someone a stinky poo head.
As an example fat Exeter ginger Archie Baele posted racist shit all over Twitter this entire summer (including at a time racist riots were happening, contributing to increased hatred and unrest) and got away with it, despite the fact his little cowardly anonymous "barry" alias was quickly unmasked the moment he went viral and several police reports were made.
To put it another way, England and the rest of the UK is not N Korea. If the average racist/homophobic/other bigot Twitter British boomer went to N Korea and said all their thoughts out loud they wouldn't last a week before being sentenced to prison for several decades.
