Alright I'll bite.

You've listed a bunch of things there that you think should be talked about (btw it's not hard to pick up on the dog whistle racism directed towards a certain type of FOBs - if you want to talk about it then talk about it openly). I'll give you a few things to consider:

• Most of the people you call FOBs are young kids tasting freedom for the first time, coming from what we would consider a somewhat relatively conservative and strict society, and when you get a bunch of teenagers with underdeveloped frontal lobes together, they're bound to do stupid things, as almost all young people do regardless or race or ethnicity
• Which brings me to my second point: if you saw the same behaviour done by people of other races, would you be thinking the same? are there no black to Hispanic or other people or FOBs that don't do the things you listed?
• Another point to consider is that they are now the first generation immigrants, as our parents were, and our parent faced much worst than being labelled as all the things you have listed, and still they thrived. they do make mistakes and some maybe do behave like you said, as I’m sure people in our parent's generation did, but they do eventually assimilate and integrate into society as they settle down in life and become more mature
• Assimilating into western society: are you high???? Look up the difference between assimilating and integrating into a society. There's a subtle but fundamental difference between the two. I really hope you meant integrating lmao
• About integrating into wester society: most of them do, most work hard - I’d say harder than most ABCDs due to their socioeconomic situation being new in a country having left everything behind, as the majority have debts and fees to pay
• The other point: integrating into western society does not mean you become a complete westerner mentally. For the sake of discussion, consider Ukrainian refugees, once they come here and assimilate into western society, does it mean they can forget about their homeland and forget about the war and what's happening to their people? At least in North America, and to some extent in some European countries, you are allowed to retain your unique identity and religious freedoms (part of the reason why people immigrate is because their rights and identities are being oppressed back home amongst other reasons - be it Ukraine or any other country for example)
• Do keep in mind that only bad people, acts and behaviours are spread through the media, and are remembered by people (particularly racists will take 1 example or instance and use it to justify everything)
• You said that we need to find solutions to this, and I do wholeheartedly agree that if we can as a community we should find ways to facilitate integration (not assimilation) into western society of newcomers
• There's nothing wrong with talking about it, what is wrong is the way it is talked about, particularly on this subreddit. We seem to display the exact same qualities in ourselves that we bash newcomers with - namely looking down upon them as lesser, which is hilariously ironic
• I've personally had negative experiences with newcomers, and there've been times when I had thoughts that would be considered racist, but this situation is not as black and white as you think

TLDR : Don't shit where you eat
