To make it short: the individualism promoted by leftists (and to a much lesser degree liberals) is anti-authoritarian, not anti-community.

When conservatives speak of community, in my observation, it's always in terms of hierarchy and submission. Be it family, state, nation, party, company, military. Consumerism might undermine 'family values', disturbing the 'moral conservatives', but at the same time, it also undermines the sense of solidarity and thus the support for policy proposals based on them and politicians running with those; and undermines the running and survival of authority-challenging communities like unions, parties, consumer groups and such. While Martin is speaking thinking of a political landscape where no major party politician dared to speak like Thatcher, a German conservative doesn't even have to be a Thatcherite/Reaganite/Anglo Disease worshipper to favor such an outcome.

Gemeinschaft vs. Gesellschaft - i.e. the longstanding German intellectual tradition of contrasting traditional style 'community' with the 'society' generated by modernity.
