> Why this particular stand?
First, any stand is better than whataboutism and just sitting there doing nothing.
Second, this stand results from my thoughts. It is my stand. There are many like it, but this one is mine.
Third, in the history of the modern world there were very few black&white situations where there was one side which was clearly the aggressor. This is one of them.
It's still better to take a stand even when there is a risk of being wrong because there is always a risk of being wrong. Don't let fear of being wrong or not knowing everything (which is impossible) stop you from standing up for your beliefs. Instead, stand up for what you believe, but be open to having your mind changed. If new information comes to light which changes your position that's perfectly acceptable.
It's a lot easier to live with yourself when you act according to your best understanding of the situation than when you allow fear to paralyze you into inaction at a time when you should have done something.
> wrong stand
But that's the whole point, isn't it? What is "wrong"? You decide.
You see people in a peaceful country getting invaded and being bombed, shot, raped and tortured? You decide if this is "wrong". I'm just saying that you should decide, rather than say "but what about something else".

I definitely disagree with this. There are many cases where you might take the wrong stand, especially where you do not have detailed knowledge of the issue you re taking a stand over.
