Is the weight of micro-aggressions real or perceived?

Up until a few weeks ago, I had no idea what the word micro-aggressions meant. I was aware of what it was but, I didn't know it was such a pressing issue. Learning about micro-aggressions has made the controversial topic much more serious for me. I believe that the weight of micro-aggressions is definitely real. Even if a few people are being effected by them, then that makes it real. It's easy to say that someone is being hypersensitive, but there are some things that just should be handled with care or left unsaid. For example, saying that someone isn't the best at math because they're asian is an assumption that people shouldn't make. Then there is the case of asking someone about their cultural background. Sometimes it may be seen as offensive when someone asks "where are you really from" even if they have good intentions. In the end, the weight of micro-aggressions is real and should be handled with care
