Everything you ever say online can and eventually will be used against you. No reason to tie your real identity into any online forum, including this one. Plenty of reasons against.
With AI pairing even semi-anonymous accounts to real people will become much easier over time.
Its fine if you never plan going to US but who knows the future right, also maybe they will eventually steer back from current direction... I am not holding my breath though. This is 50% of US population, consistently. Don't forget orange man didn't win previous elections only very narrowly, US folks on the ground don't give a nanofraction of a fuck about other nationalities and love this style of government. Out of 3 attempts, he won twice easily and 3rd time almost.
Stay the fuck away from US and any US product in literally any form, best advice for 96% of mankind currently.
