I would like to let you know that I am extremely unhappy with your new censoring policy. I am appalled, by you forcing a project to change its code because of the use of the work 'retard'. That is frankly just ... . As a consequence I will not start any projects on github anymore, but maintain the old ones. I will use bitbucket in the future. 
I really hope that you change your policy and let your fingers from peoples code.
