AIO for calling my very white uncle a racist for sharing this post??

For clarification he’s my uncle on my dads side & I accept that we have different views on politics, BUT when I seen this is actually upset me, considering that I’m Mexican and have family (on my moms side) that could be deported at any moment. I understand wanting people to come over legally but there’s a whole lot better ways to word your opinion on that. Pls tell me I’m not overreacting (THIS IS NOT A POST TO TALK ABOUT POLITICS, so please don’t start any arguments, everyone is entitled to their opinions)
