It seems that students are not harassed for speaking Spanish in your school department. That is definitely not the case for all public schools around the US. I have had to move a few times. So, my kids have gone to public schools in several states. I’ve gone to school department meetings, in several states, to advocate for my kids right to speak Spanish. I’ve found public school departments quite conservative and the one’s I’ve attended, have backed the notion of English Only, as non-discriminatory and in the best interest of ‘Teaching and Learning’. A few school committee members have backed me, and some encouraged involving the ACLU, but I was also warned by conservative members that legal action would result in cost to the school, and thus taxpayers, and could have negative consequences for our relations with some members of our community.
So now, when I go to school, I speak with my kids, and other Latinx teachers in Spanish. My kids and most teachers respond in English. However, a few fellow socialist/communist Latinxs do respond in Spanish: Pa’l carrajo los racistas, facistas, trumpistas.
