Wasps have played in various places in London from 1866 until 1923 when they moved to Sudbury in London and stayed there until 1996 when they moved to Loftus Road before moving to Wycombe, which is approx 20 miles from London. They've now moved to the Ricoh which is over 90 miles from what Wasps fans would consider their home.
You are equating that move to us moving approx 3 miles over the city boundary. They aren't even remotely the same.
The criticism here about wasps is because they are coming to a different town. Yes it's 90 miles. But the criticism would be there if wasps had moved 4 miles. The hypocrisy is that when it suits, I.e. when CCFC move into someone else's town it is ok, but when anyone comes to Coventry - Wasps, Blaze - it is " just wrong ".
