The libs have finally learned a new word! Just like tankie it’s actually an old word that gets misused, but they have learned a new word! Looking forward to seeing it everywhere.
If you don’t believe me then check the modlog: This meme got removed for being “campist” 
They’re using it more and more
Alliance or Unifying ideology I like = Pragmatic liberalism
Alliance or unifying ideology I don’t like = Campism
OP’s meme is clearly promoting the ideology libs don’t like (anti-imperialism/BRICS) instead of the the ideology they do like (liberalism/NATO). Therefore, it’s it’s campism.
