The only way a violent removal occurs is if our government completely ceases to function, beyond the point it can organize its military, which lol not happening.
or if ur government actuslly stops being retarded and begins to send em back to india, and makes life hell for them if they stay
u can do a lot of things to get em to leave
for once, u can pass laws that would statistically cause a lot more harm to indians
if they seem to drain welfare disproportionately, just cut it off from anyone who is an immigrant from certain regions or belongs to a family of such immigrants
if they seem to wear turbans and build temples to vishnu everywhere, just ban religious headgear (and refuse to enfoce it on christian headgear) and mess with zoning laws to give you the permission to demolish their temples whenever one pops up
they shit in streets? well, make it a jail-time offense and deport em once they leave
they do phone scams? well, catch the hawala brokers who clandestinely transfer the money to india (legally hawala doesnt transfer money, it transfers debt, and nothing's written down anywhere), this will not just shut down indian scams, but also nigerian, somali and arab scammers and terror orgz, these guys all use hawala cuz the actual money doesnt move, only an informal agreement of sebt between two brokers
but if u catch the hawala broker, interrogate him for all his contacts both in europe and india
and everything he knows, and use that knowledge to prevent hawala transfers, now the jeets can't send money back home without it being tracable to them
which makes scams infinitely easier to spot, but also prevent jeet work migrants from readily transferring money to their families back in india
speakingof which, tax any money transfered to any migrant-sending shithole (india, pakistan, sudan, somalia)
hell, if u can get away with it outright ban them from using any public services at all, all of the amenities of a first-world country are now outside of their reach
tax em every month for simply being in your country, eventually they'd be poorer and more miserable in europe than they are in india, then leaving will be the better option
in the meanwhile make sure they know that if they leave, you'd pay for the flight back, even if it's in first class, u want to reward em for leaving and never returning, and punish em for doing anything that u dont want em to do
to be more precise, u should have a list of countries you block any new immigration from, and do ahything you can to inconvenience (and reduce the threat) the ones already in, while also giving them a free plane ticket back to their home country, they can go back any time they want, if they don't, we'd make every aspect of your life miserable
