And what exactly wrong with what he said? He differentiated between God and some god by lower-casing the word.

His implication is that you are a moral egoist, whom assumes that most of the people in the world would find it acceptable to run around town during a pandemic, visiting social places, increasing the risk of the spread of the disease, (instead of staying inside to protect self by protecting the society, because a human without the society can't exist).

So, geven that you're a moral egoist and not someone whom strives for moral perfection, we can make a conclusion that you don't understand what God is and you have some god in your life instead of God, from whom you get your morals.

Let me help you out: your morals are all wrong, which suggests that your god needs to be replaced.
