You cant ban anyone so please avoid talking about bans since there isnt any consensus You are just trying to impose your will regardless of the facts other people are providing to back their statements without backing YOUR statements yourself This map made by Renato Biasutti is more than enough It clearly shows that for instance in Veneto  of blond people is from three to seven times higher than in Calabria and in Tuscany is at least three times higher than in Sardinia This is definitely relevant Now of course you will say this map is  old but you wont provide a newer one  not credible but you wont provide a more credible map  same difference as other countries but you wont provide a single source proving that Etc  Try to stick at this map What is wrong about it As long as people wont provide sources to back their statements I will consistently restore any reference in the article
