Your missing an important aspect. Those sites you mention as a rule don't have any holidays or commemorations incorporated into their logos or sites at any time, Google does. Google manages to remember every lefty and pagan "day" celebrated regularly.
Halloween:
International Women's Day:
Martin Luther King Day:
Earth Day (every year)
Ray Charle's birthday:
They purposely leave out Christmas every year and now have sunk so low as to "forget" memorial day this year. You mean to tell me they can commemorate Ray Charle's birthday yet not our war dead?
From now on it's dogpile for me. Goodby Google.
