Increase in non-indigenous activities in the UK?

In the last few years I've noticed a huge increase in non-indigenous activities in the UK, and wonder if our slack immigration policy is to blame. Pole dancing is especially popular where I live, where there are even cles teaching this! This is obviously due to the m influx of Polish people. What can we do to discourage such dancing, especially in nightclubs and bring morris dancing into nightclubs instead?
