So you're telling everybody here that you feel insecure when the other person uses the word "insecure"?
Seems like a classic case of meta-insecurity: you're insecure about debating insecurity at all.
But fret not. You are not alone. Everybody has insecurities, and most insecure people feel insecure talking about insecurities, whether their own or those of a third-party.
It is often possible to learn how do deal with one's insecurities, it's called COPING and DEFENSE. Defenses consist in avoiding the causes or consequences of insecurity. Coping consists in dealing with unavoidable consequences of insecurities.
Dealing with insecurities by COPING and DEFENDING yourself / your ego is an adult thing.
Children don't deal with insecurity. They instead latch onto the belief they're in a perfectly secure world... until they learn they're not in a secure world at all, in fact they learn the world is a place of very little security, and that children (who, paradoxically believe themselves secure) are the most vulnerable of all, and that his previous sense of security was an illusion. A trick of his brain chemistry to entice him, as a child, to repeat rituals, beliefs, actions learned from adults around him. Just like a small deer learns how to avoid poisonous plants from observing his mother in proximity, humans become repeaters of habits that they learned when they felt secure, in childhood.
99% of normies' senseless rituals are attempts at regaining an illusory feeling of security, in the magical sense, by repeating other rituals they observed as children.
Smalltalk, for instance, of the kind "Good morning, Sir, how are you? I'm fine, thanks. And you?" is actually a magical spell that gives normies a false sense of security --- "

this nice guy who is wanted for murder in 3 states and has a suspicious looking boxy bulge at his hip was polite to me, so he totally is not an armed psycho plotting to kill people, unlike that autist over there that walks staring at the floor so as not to hurt ants and milipedes, and is totally a terrorist threat armed with his underutilized penis of mass destruction". If it seems silly, it's because normies are silly.
