Yes we should always advocate for justice and speak about injustice. However, we must use effective means and strategies. Use strategies that are more effective an subtle, because as your parents said, you also don’t want to bring harm to yourself or your community. Don’t say things that will make you and your family be monitored or targeted. Use terms that are more neutral and an effective method is to search for what American figures have said about these atrocities and circulate that. You’d be surprised how many Americans condemn the types of injustice you mentioned. That would be a safer and more effective way.
