"Common sense and decency" are subjective. E.g. things which for me are "common sense and decency" for You are probably "fascism".

I would say you’re probably right.

Anyone who says that decency is subjective is probably just looking for a way to excuse their own lack of decency and compassion toward others. Right & wrong is usually pretty simple (e.g., feeding people is right, and starving people is wrong), but self-interested people like to pretend otherwise.

It just that the most people consider their own ideology as "not ideology at all, just, you know, basic human decency, common sense, universal human values, it is really simple!". From my POV You leftists are lacking "decency".

“You leftists” identifies you as someone who hasn’t a lot of decency.

Saying that identifies you as someone who hasn't a lot of decency. We can do this ad infinitum.

Yes I appreciate it is confusing for you.

Sorry, but is You who are confused. You cannot understand that "decency" is purely subjective concept - so of course that I lack "decency" from Your POV. Just like You lack "decency" from my POV.

Yes this is where you are wrong. Maybe one day you will have greater clarity on decent human, unalienable rights. Read that poem.

Maybe one day You will have greater clarity on how your religion of "human, unalienable rights" is silly. Although, if You are currently in the phase in which You consider any poem as an argument, it will probably not be soon.

Funny thing. When I discuss christians they are the same "uuuu, nooo, you cannot criticize our morality, because it is objectively good, contrary to yours!!!". Christianity and leftism are so similar.
