No, but it does show you need to resort to insult in order to argue, which in turn reveals the weakness of your beliefs and hurts your own advocacy by not putting forward the best form of your argument.
You can genuinely believe something insulting. And for what it's worth, I don't think you genuinely believe this. It's much more likely you're using a pathos appeal, as your logos argument has failed, which I'm telling you actually weakens your ability to execute your own goals, as it's entirely transparent.
