All this is what it means to be alive. We need to come together in order to be alone together in this place we call ours. Of course there are immeasurable advantages to be gained from associating with other people, especially in waging war against the evil vermin who are riding roughshod over our liberties. Individualism means simply that each individual is an end in himself, a sovereign entity who may not be treated as a means to the ends of others at gunpoint. Being forced to marry a partner chosen in advance by the seniors of each family - THAT would be collectivism.
Collectivism is the doctrine embraced by every party in parliament.
It is also endorsed, incidentally, by the Business Roundtable. Through these vehicles we can indeed strive collectively to fight collectivism. I hope it's clear by now that there is no contradiction involved. A freely chosen association is an expression, not a denial, of individualism.
