Yes it is unkind. We should be respectful, yet disagreeing.
It's fine to call them idiots. They deserve it.
Idiot and bigot are both terrible words.
If you disagree with a person's personal beliefs, then that's all there is to it. Insulting them for it is just rude.
Even if their belief is idiotic, by telling them they're an idiot, you're hurting them. More often than not they will not change their beliefs in the face of insults, so nothing positive is gleaned from calling them an idiot.
Outright calling anyone an idiot is disrespectful, regardless of whether or not the person was truly being an idiot. To call a person an idiot based on his/her beliefs is even worse-we all have freedom of religion and that should be respected.
Even if someones belief sounds idiotic to you, try and understand that person's viewpoint before calling a person an offensive name. Honestly, I find it quite immature to outright call someone an offensive name just because their belief is different from yours or you are not able to comprehend why that person feels the way he or she does. If you don't understand someone's belief just ask that person what has persuaded him or her in their belief on a topic.
if u has nuthing nice 2 say, don say anything at all
Some people think that a belief in something like Santa is reason enough to belittle someone, but I disagree. First of all, I live in America, which grants e the freedom of believing in whatever I please without persecution by the government or society. Secondly, if he belief in Santa makes someone a happier, more pleasant person, wouldn't you rather keep hem that way? Why spoil their childlike innocence with negativity. Thirdly, it is very possible to disagree with someone in a pleasant way that results in little conflict. Don't go starting trouble wen neither of the disagreeing parties are planning to give in.
Atheists will burn in the hellfire, their faces will scold, their intestines will disintegrate and their eyes will explode. That fire is 70x times hotter than the worldly fire and if they will be dipped in this fire they will forget all their luxury that they have in this world.
There's nothing wrong with disagreeing with someone but it is wrong to attack someone for minding their own business.
It's not "unkind" to call somebody an idiot if they put a belief over reality & facts. If you try clinging to a belief despite facts telling you that you're wrong, you're an idiot, stupid or whatever word you're like to use to describe a lack of common sense or intelligence.
If people decide to hold onto ridiculous superstitions, then yes. This also can apply to religion since many people view their religion to be the right one while there are other religions that go against their religion and etc.
Some people out there have crazy and irrational beliefs that do not deserve respect, take the KKK and ISIS for example, they are radical immoral idiots whose opinions are not worth my time to even begin trying to comprehend.
Depends on the opinion. If simple science and logic proves them wrong, then yes. If their beliefs can be proven to be false, still keeping them is idiotic.
