When I criticize circumstances or a person who caused something or did something that is worsening something's or someone's current situation, people tell me stuff like "do it better yourself", "you do the same", etc. and just instantly kill the whole discussion. Most of the time I am aware that I do those mistakes too. But apparently me having done what I am criticizing is enough for people to not even discuss the problem with me or declare all of my arguments as invalid because "but you".
This isn't only the case when I am the one doing or having done the mistake I am criticizing. It is also the case if the person or institution who I am siding with in a discussion is doing or has done it.
Sometime ago, German media was criticizing that there were cases in Turkey where people were way too long in custody before being presented to a judge or even properly looking at the case. When I tried to talk with people around me about that, of them just argued "Well, that stuff also happens in Germany." and just stopped the discussion because of this empty phrase.
How do I deal with this? Whenever people use those killer arguments, I think to myself "well, that's true but that doesn't change the current situation at all. It just hinders progression." I don't know how to properly convey this thought of mine to people who seemingly don't want to discuss in a fruitful manner.
I want them to understand that those arguments aren't enough to stop the discussion. This is just an assumption, but I don't think that those people think they are souring the conversation. I feel like they are genuinely thinking that using arguments which fall under the category "but you" are arguments which have any validity. To me these "arguments" feel empty. I don't want to come over like I am better than them. I am not. If my attitude towards this problem is wrong, I would really like to hear why.
My primary goal is the situation's improvement. When I am criticizing someone, it isn't just for the sake of criticizing or being on a moral high ground. The most famous occurrence of this is when someone goes on and on about how bad something is but doesn't do anything to improve the situation himself.
