Of course as Muslims we are always going to dislike what is going to send us to the fire.
Your examples are of social interactions, which if they have anything to say, is approach that person instead of gossiping, and letting them know, and its up to them to heed and repent. I was working with a Muslim girl who was in a relationship with a Sikh -it has ended and she has now married a Muslim, but I did not go around telling everyone, and slandering her.
I do not treat people as if they are dumb, as lets not forget that they are capable of being judged on the Day of Judgement personally by Allah-so I'm not going to treat people as if they are stupid.
Also do not forget as of course the focus is on the people weaker in Islam, that others do not want to associate themselves in bad company -as it may lead them to the fire too.
Being judgemental is too much of a Western phrase-when they don't heed the message from Allah. Allah has already given us the rules, so if someone does not abide by them, it is not arrogant to think that so and so is doing wrong! WE don't have to go to Heaven to find out if a person being lewd, wearing revealing clothing is wrong-as Allah has already taught us that it is wrong. I have even heard lewd females say only Allah is my judge-but Allah has already taught us that Allah dislikes what they do. Allah is not going to call us arrogant for forbidding evil and enjoining good.
When teaching Islam, for me I will always be direct, which people are aware of away from the internet. I do not however tell others what to do, as Islam is a fair easy test. Ie there are some Muslims who think they can make someone the "perfect Muslim" by telling them to be it, when it will be upto that person as of course Allah is testing them to be good, it is not my test to make someone a Muslim, if it was then how would they earn their reward?
So for example people have complained about music, and there are people who don't like the TVs, well I am not into dramas etc, but I am not going to hound people and tell them its wrong, when music was present at the time of Prophet Muhammad peace be upon him, but of course music today is just sick. There are people who harshly treat people, people know where I stand, and they don't interfere with me, and I don't with them. So personally be kind to people. When people ask about Islam, there is only one right way, and I am direct and formal as I am not wasting people's short amount of time in this world. This is what I constantly remember when I write, as of course people who are being tortured in the grave would wished to be in our position, but they cannot.
For me, I will always listen to people who are standing by in Islam. Not waivering (to people who want to change what Islam means), and people who complain about people who speak about Islam, I do not agree with. There are those that use religion to oppress others. The point again is that we talk about the truth, we are not here to change people-that is their test. Allah has NEVER said its our job to change so and so. Allah has NEVER said its our job to make someone a Muslim-its actually their own goal, job to make themselves a Muslim, I am only responsible for my own soul. So you have to make yourselves good that is why Allah is rewarding us individually for being good.
