It makes political sense for them to demonise certain groups. The childfree movement has been quite vocal (or at least well publicised) of late, and it’s super-easy to cherry pick some of the more extreme viewpoints from that ‘community’ and weaponise it against ‘normal’ people, conflating those opinions with the so-called left (as if deciding wether or not you have kids defines who you are politically). It’s easy fodder for the media and, as always, successfully distracts much of the population from the fact that they’re being bled dry by billionaires.
