If you think that personal attacks on other wikipedians are OK, then please advocate for the "no personal attacks" rule to get repealed.
I advocate the enforcement of the agreed-upon rules that are specified in [[Wikipedia:Policy]], which happens to include [[Wikipedia:No personal attacks]]. Your characterisation of the desire of wikipedians that personal attacks should halt as 'Mommy, he called me xxx" and "whinging" is both condescending and illogical, given that "no personal attacks" happens to be a wikipedia policy. I have quoted it before, and I shall quote it again (from [[Wikipedia:No personal attacks]]):
Sorry, no. I am not going to try to change the policy. Rather, when a case comes before the arbitration committee that consist of nothing more substantial than name-calling, I will recuse myself.
Vandalism, yes. Explicit threats, yes. Edit wars, yes. Insults? You're not paying me enough to tell people not to be hostile or rude. I'd rather relieve Sisyphus for a millennium or two.
My characterization is "illogical"? Non-sequitur -- I'm not a Vulcan. "Condescending"? You're absolutely right. After all, my /six-year-old/ doesn't need my help to handle simple name-calling.
