What a nasty bigoted comment.
And I suspect 100% bloody WRONG. And even if you're right, so fucking WHAT? 
I didn't go, as I said on another thread, it would be a 13 hour round trip for me as I live in the sticks and nowhere near a train station and 250 miles north of London, I physically could not stand there that long, and it would cost money I am not prepared to spend for the train fares/underground fares/hotel etc, as I couldn't do it in one day because of the distance.
I have been to things (way back in the past,) where I queued for many hours, and I was cold and hungry and in pain from standing up so long, and it cost me a bunch of £££, and I ended up seeing very little.
So I have been viewing it all happily from my living room, where it's cosy and warm and I can see everything and everyone close up. If I had lived in London, I might have actually considered going, if the queueing time had been 4-5 hours, but like fuck would I wait 20 hours+ and overnight etc, in the cold.
Last time I waited awhile for something, was about a decade ago when me and DD waited in Leicester Square for 5 hours to see our fave film star when their film was premiering there. Totally worth it as we were in the front row, and they came right up to us and spoke to us, and we got a selfie with them.
But as for waiting for 20+ hours in the cold - and overnight too - to see a coffin for 10 seconds, No. I loved the Queen, and am a Royalist, but no. And I genuinely can't fathom why people are doing it. I just couldn't, and wouldn't.
