There was alot of racism when I was a kid in the 70's, as in they were not bothered who hears them saying it and some would cross the road to shout in your face.
Then in the 80's it was less obvious, more "I'm not racist because my aunt 's sister is married to an Indian/ Pakistani/Bangladeshi but....(insert racist comment or viewpoint)"
In the 90's not experienced any and looking back, nobody tolerated any racism in any way shape or form.
In the 00's started to creep back with hidden comments in conversations but told not aimed at me as its them just making an observation and comment about what is in tbe media, so I shouldn't feel it is aimed at me.
Nowadays - have had people ask me to justify and explain why terrorists do what they do. Have had people ask me my opinion on how I feel about any media report involving Muslims or terror. Asked how I feel about Shamima Begum and whether I agree as a muslim on her not being allowed back. Then being told they asked me as I'm muslim and no one else on the table being asked.
People telling me to go back to my country, and tell me to go back to my parent's or grandparent's country when I tell them I am British and was born here and have no other home. Then told I may be British but I'm not English so should go back to where my lot came from.
