Don't push the preparedness onto others. Your language and your heavenly yet SO Un-Divine IK's language are third class, and this isn't the first time. No matter how much you hate someone, OR someone has done wrong, specially elderly, no matter what the title is, you can STILL show your hate and anger against them in a respectful way. THAT was the point that IK's followers in that crazy mental set usually miss!!
I asked you, if I decide to hate your father, and called him what you were calling NS, would it make the use of third class language OK??? NO, it doesn't!!!! Your father in this case, no matter how many bad things he may have done to me, or even if I am just accusing him, neither aspect still allows me to use bad language towards him. Just because, 1: he's a human, if he's really done wrong, I don't have to get down to his level, otherwise what's the difference??? 2: He's elderly so I have to give him respect for his years over me.
Now these two conditions, everyone should consider out of respect before writing any crap. Its just a human courtesy. The language you are using today on here, is how you are in your household too (psychology), just like IK's bad mouth outside and at home. So today you are doing it, tomorrow, your kids, or siblings will be doing it too. And if you don't like it then , well, you should've stopped doing so!!
