Actually, people weren't talking that much about Iran before --it's just because it happens to be the current target, so western media plays Iran a lot.
It's also for the same reason why people DON'T talk about Saudi Arabia, which is 10 times worse in those aspects than Iran --but since it's an ally, it doesn't get played unfavorably much, if at all.
Now, what are things that are "by any definition wrong"? Who gives the definition? Let's see your examples:
"""You simply cannot, in any modern society, discriminate against someone because it happens to be a woman, or throw stone at someone until they die because you didn't like his opinion."""
In the US 50 years ago there was prevalent racism against black people (heck, there were hotels/restaurants etc not accepting them as customers).
Was that civilized? No. So, would another country be justified to say, bomb the US and topple the government to pass laws to change that? I say, no, the people of the US would have to do it themselves (as they eventually did). So, why should it be different for any other country?
And who says that all countries should get to the same level of "civilization" at the same time?
For example, besides abolishing slavery earlier, tons of countries had women voting much earlier than the US did. And tons of countries have abolished the death penalty already.
You say "you simply cannot, in any modern society throw (a) stone at someone until they die because you didn't like his opinion".
And I say, that in modern societies like the one I live, you simply cannot execute anyone AT ALL, whatever he said or did. It's unacceptable. When is the US going to come around to this one? And how is stoning worse than the (horrible) electric chair or the (disgusting) gas chamber?
Still, americans have the right to do those things (to one another), if that's what their society wants and believes in. People are not justified to call them "evil" because of that, nor to try to topple their government. The same should hold true for any practice of any SOVEREIGN nation.
I don't even care if they are cannibals in country X, let them do what the f... they want. No one should dictate how other societies should live.
