Acts 5:40 And they agreed with him, and when they had called for the apostles and beaten them, they commanded that they should not speak in the name of Jesus, and let them go.
Do you get upset when many people turn out to support someone who is doing something wrong or even against the law?
I know I do get very upset when I see people getting carried away with their feelings and following the wrong path; but that is part of being human and emotional.
God has given us the ability to choose between right and wrong and He warns us we may well face a lot of opposition when we stand up for what is right. That should not stop us from standing up for the truth!
