"I Welcome anyone into the UK willing to fully integrate into traditional British culture and not try to change it. Being inclusive doesn’t mean blindly accepting other cultures diluting yours."

Look, things change ok? Occasionally that's because of immigration or adopting from other cultures. I for one am very glad we're not all stuck with meat and two veg meals every day and can access pizza, pasta, curry and all sorts of other nice food.
And while I'm on the subject of food, if you're going to be nostalgic about past times, if you go back to ye olde times before the wars actually lots of people didn't get meat and two veg and subsisted largely on bread and cups of tea. A substantial proportion of army recruits signed up for the First World War were rejected due to being malnourished, 15 year old working class boys were on average only about 5 foot tall. We have problems with poverty and inequality now, but nothing like that.
We also have different technologies now, greater acceptance of being gay, much less acceptance of sexual harassment in the workplace. Once, churchgoing was 'expected', now according to the figures OP cited just 12% go at least once a month. Culture doesn't stand still. It just doesn't. And OP, it's not just about the big bad immigrants.
Edit: cross-posted with someone else saying regular church attendance is less than 5%.
