Muslims, unlike the Jews in the ‘30s, are resistant to integration

I regularly see stickers on lamp posts telling me that this or that street is a gay or Jew-free zone thanks to a range of Muslim groups. I see elderly women and men who have lived here for decades but don’t speak any English yet still know what day to go collect their UK pension.
I see their sons and husbands hanging around mosques every Friday who dress like they are still living in their former country even though the clothes they wear are not compatible with the UK climate.
