Regarding your uncivility 

I notice that you keep deleting my kind reminder to retract your personal attack or to apologize. This seems to be hard for you, which seems to indicate that your incivility was on purpose. I hope that's not the case, and that you will show maturity and retract the comment you made. Shouldn't be that difficult. In any case, I found this: https://en.wikipedia.org/wiki/Wikipedia:No_personal_attacks It's a policy, and you are required to follow it. Thanks, and kind regards from a russophile.
