That's an amusing claim given that most of these parties don't even get enough votes to get seats.

Pray tell which of your "biggest parties around" is it that you believe are socialist in anything but name?
I find this idea of a communist takeover bizarre: You've gone from a country with armed marxist guerrilla movements fighting a right wing military dictatorship, to a country where the president is an ex-marxist guerrilla.... Yet she represents a party that is no longer any further left than moderate social democrats, and hear policies places her pretty much as a centrist by European standards (and we don't have many actual socialists any more either) - heck, some of what she's done (her inflexibility in dealing with strikes, for example) would've made Maggie Thatcher proud.
Party fragmentation is a non-issue, as they'll get combined. We are suffering a communist takeover - in everything but name - from some of the biggest parties around (including parties that used to have "liberal" on their name just shortly ago). Those parties that call themselves communist are quite divided, some supporting and some opposing the takeover.
