You're making a straw man caricature out of the nativism detractors. Current researchers do not claim that first language is taught, that's why the field is called language acquisition regardless of whether one subscribes to nativism. The more nuanced non-nativist theories argue that grammar learning employs domain-general cognitive mechanisms, rather than language-specific innate grammar knowledge or principles. It's quite a stretch to connect any of this with political ideologies.
