Romance languages have gender much more deeply ingrained in the language and present far more challenges in attempting to de-gender them. So, if the progressive attempts to respect the culture of others and be welcoming to different cultures, that can come into conflict with attempting to remove implicit bias that may (or may not) be connected with language (with the claim being that saying businessman inherently discourages non males from pursuing business).
Disclaimer: I'm not very political and align myself largely with moderate democrats with some libertarian sympathies at time. I have nothing against the ideals of re-examining previously held notions for pursuits of greater equality, just an interesting conflict in my opinion with political relevance. I find it fascinating that Trump improved margins with Hispanic voters over past Republicans and I find myself wondering if it wasn't so much about him as aspects of the progressive/democratic movement.
