I said that despite having different ideologies both Hitler and Stalin behaved in similar ways in that they both deliberately persecuted and murdered people because they didn't fit their personal 'ideal'. This makes them a different sort of person to a leader whose political actions result in loss of life.
You said that they their ideologies were irrelevant and that they were morally the same because their actions led the deaths of innocent people. If that is your view then it doesn't matter why Blair or Bush ordered the invasion of Iraq and Afghanistan, the fact that it directly led the deaths of innocent people makes them morally the same as Hitler or Stalin.
If you're now saying that the ideologies and behaviors of the leaders and the underlying reasons behind the deaths DO impact on whether they are justified or not that's fine, but I'm going to ask why.
Why, in your mind, is Hitler ordering the destruction of the Jewish people different or worse to Bush and Blair ordering the destruction of Islamic Fundamentalists?
Why was Hitler trying to enforce Nazi ideologies on Europe at the expense of millions of lives worse than the US and UK trying to enforce Western ideologies on the Middle East at the expense of millions of lives?
It's ridiculous to imply they are similar - much as I disliked Blair I don't recall him systematically removing peoples human rights and putting people into death camps.
You don't remember the coalition systematically abducting, torturing, and imprisoning (without trial or charge) anyone they suspected of being a terrorist regardless of whether that suspicion was justifier or not? You don't remember the same coalition using drones and other means to summarily execute people they deemed a threat?
Do you genuinely not remember those types of incident or are you just downplaying?
