Calling all lemmings: Critical Mass, then a celebratory "after-party"

These two notices (below in italics) appear on the SF Bicycle Coalition's online calendar with this hypocritical disclaimer:

*Events not officially sponsored or organized by the SFBC are marked with an asterisk. We post events that might be of interest to our SF area members; we do not necessarily endorse any particular group or perspective you may find represented here. Contact us with questions.

Here's my question: Can the SFBC cite a single event, group, or perspective it has ever listed on its calendar that it didn't endorse?

Notice that the Critical Mass "After-party" is co-sponsored by Supervisor Mirkarimi, a longtime supporter of the illegal, traffic-disrupting monthly demonstration by the city's bike people. Funny but in his campaign literature Mirkarimi doesn't mention either Critical Mass or his vote to make the Bicycle Plan part of the General Plan, even though it had had no environmental review, which the Superior Court found to be illegal. Nor does he mention his leadership to "reform"---i.e., eliminate---level of serice (LOS) traffic studies for projects in San Francisco. Once Mirkarimi's bogus LOS reform is in place, the city will be able to quickly take away street parking and traffic lanes all over the city as envisioned in the city's ambitious Bicycle Plan.
