Was what I said sufficient, or would it have been better to disregard it? And is it permissible for me to ask someone who is accused of extremism, or who accuses others publicly, about the pillars of prayer in front of them, and if he doesn't answer, I inform him how can someone who doesn't know the pillars of prayer judge whether this person is an extremist or not? Or does this contradict the principle of loving for your brother what you love for yourself?

A believer may be tested by those who mock him for his religiosity, so he must be patient and repel evil with what is better. The issue of the face and hands is a matter of scholarly disagreement, and there are evidences for both sides. A Muslim should not seek victory for himself, portraying it as a victory for religion. A believer manages situations subtly rather than argues, and spreads the wisdom of Allah. It is better to avoid mixed gatherings with women, especially those who do not adhere to the legal head covering (hijab (definition)).
