it's about showing the fundamental reason behind that action.

You are being reasonable. I think the issue is when I am trying to be reasonable but then the other person who got downvoted just gets mad and would rather have a battle of wits. I am not a huge fan of battle of wits; just not productive imo.

I will keep working towards downvoting while trying to educate people on the reason; in a way that is sustainable for me.

The reason many people downvote and do not give a reason is the conversations are rarely productive.
