In fairness I have never seen anybody dab, on the street, in London, where work/live. So, if there are some who really are addicted to dabbing, they should do this in their own home.
Regarding being gay, if you want to practise this, then do it in private.
You seem to think that a personal CCTV camera will follow you around, in Saudi Arabia - this is not the case.
As long as you are sensible, you won't be arrested for dabbing or being gay.
Remember, every nation has it's own customs. Just because those customs do not synchronise with English customs, it doesn't make that country bad. For example, I fully support the no alcoholic drinking rule. It improves health, lowers crime and hooliganism. Those in the middle east would argue that England is crazy for allowing alcohol.
