But dissent from what?

Dissent from something obviously true?

Dissent from something obvious false, that no one has said?
(like 'Everyone should switch to Pythonx.y')

I have several 'gripes' with 2.7 and it is currently useless to me. 
Should I let them be known? How many times?

Do you agree with me that the same criteria for gripe legitimacy should 
be applied equally to all Python versions (even if we should disagree on 
what those criteria should be)?
