I haven’t focussed on Iniesta. Iniesta made the right decision to take down the tweet and apologise for it. Iniesta himself wasn’t personally dressed in blackface. That should be the end of the matter, as long as he knows the symbolism of blackface going forward.
My problem is with neanderthal cunts like yourself and @tazdedub who are offended that racist stereotype are rightly seen as unacceptable.
Spain lags some way behind in terms of knowledge about these sort of symbolic acts that are considered racist. See the Spanish basketball team posing for a group picture while they all did a slanty eyes gesture in 2008. The blackface thing is extremely culturally sensitive in the US and UK, but perhaps less so in other countries, perhaps partly through ignorance, perhaps partly through wilful stupidity.
