I am married to a “legal” immigrant and I can promise you he doesn’t dislike illegal immigrants. Exaggerate much? I am certain there are many legal immigrants who don’t want you speaking for them. FYI many immigrants who are at one time here illegally later get green cards. I know you can still get a green card based on marriage even if you are a visa overstay, as one example. So it’s not nearly as clear cut as all legal immigrants were always here legally.
