Genuine question, especially in Scotland where, for example, you can get married to anybody by anybody (with a licence), anywhere you choose.
TBH I can’t think of anything connected to religion (barring the usual WoS OO pish) that has ever had an impact upon my life or that of my family.
My two daughters are primary 4 and primary 2. In each of their classes there are a number of muslim children. So far as I know neither they nor any of the other non-muslim kids in their classes haver every been invited to a birthday party or play day with any of the muslim kids (the converse is not the case).
Last week my eldest daughter had a class trip to the Glasgow Central Mosque. She had to cover her head, arms and legs to go on the trip, as did all other girls in her class.
I consider both of these examples demonstrate a negative affect on those involved and society in general. So far as I can tell, both are a direct impact of religion.
