You are too harsh.... Kafir, taghut..??? Sheer bunkum. You could phrase in a healthy way. Work on your akhlaq. I dislike their ruling class too, but I try to follow Islamic ettiqutes.
What is your definition of "phrasing it in a healthy way"? Most likely, what you mean by that is, "You can beat around the bush and not call a spade a spade." I never do that, and never will. It's foolish. It wastes time and confuses things. Rather, be frank and straightforward always. If something is Haraam, say "This is Haraam." Don't say, "This is, sort of, something that, maybe, possibly, isn't 100% permissible, and it's like, not Very good to do, and it's sort of better if a person were to not always do it, but that's just what I feel, and I'm not judging anyone."
What's the need to make such spineless statements? It wastes the time of the reader. Cut to the chase. Let me ask you something: Say you're in a room with someone. There are a bunch of bottles with maybe water or juice inside, and one particular bottle has poison in (hypothetical situation here). This friend of yours - unknowingly - picks up the bottle of poison and is about to drink it up. What are you going to do? Are you going to make a bunch of long-winded statements about why it's better if the person rather doesn't drink all of it, or are you just going to be straightforward and say, "Hey, don't drink that! It's poison."
?
The `Ulamaa have to clearly come out and say what is Haraam and what is Kufr so that people can avoid it. That's their duty. Haraam and Kufr is infinitely worse than poison. Poison only harms a person in this life, whereas Kufr destroys their Aakhirah forever. So which is more dangerous? Then, when it comes to something as dangerous as Kufr, there's no room for playing around. You only play around when you take the Deen as a joke. You don't take it seriously. You don't Really believe in it.
People should be honest with themselves. When it comes to saving a person from some worldly harm, like throwing them out of the way of a speeding car, they'll praise a person who does that despite the force he used to get the job done. He threw them out of the way. He didn't stand around speaking in a long-winded way about the harms of standing in the way of an oncoming car driving at full speed. In fact, they'd call him crazy if he did that. They'd say do what needs to be done to get the person out of the way and out of danger. So then why do they not feel the same when it comes to getting the person out of the way of Kufr, out of the way of Jahannam? The `Ulamaa know that this particular action leads to Jahannam, so they tell people, "This is Kufr! Stay away from this!"
The only people who will get upset when hearing that are people who don't truly believe in Jahannam. If they truly believed in Jahannam, they'd appreciate being saved from it.
How foolish is Insaan...
