CMV: If you think “not all men” trivializes the issues women face by men, then you should feel the same way about “not all immigrants”.

Let me start off by saying that I think both of these statements are stupid for various reasons. I’m also not some altrighter trying to bait this subreddit so mods be nice. That’s not the point here though. 

On social media I often see women make fun out of men who say “not all men” in response to women sharing their stories of being harassed, catcalled, etc. 99% of all women aren’t stupid and obviously know that it’s of course not all men who do this, but it’s significant enough that they feel like it’s a story worth sharing.

How about this then. During New Year’s Eve 2015/2016 over a thousand women in Germany were sexually assaulted, primarily by immigrants from the Middle East. What do people respond to this with? “Not all immigrants”. Particularly, there seems to be an overlap with the same people complaining about r*pe culture who also suddenly decide to say “not all immigrants”.

So which one is it? Because you can’t say one without saying the other. You’re generalizing an entire demographic and you can’t minimize one without minimizing the other, or vice versa. Either you say “not all X” in both cases or none at all.

Change my view.

The speaker and the point of the conversation are important here.

In the first case, you have a woman sharing her personal story about being assaulted, harassed, catcalled and some guy making it about himself and commenting "not all men." And not only is he making it about himself, he's not so subtly accusing the woman of sharing her story as being sexist.

Now your second example isn't about a personal experience is it? It's a conversation between two observers of the event, a political/social debate, rather than between a victim and a random commenter, yes? 

One observer who uses this story as an example to support their anti-immigration views, and another observer who disagrees with the anti-immigration agenda.

In this case, saying "not all immigrants" is acceptable. This is not a person trying to drown out someone else's story, it's a person making a point in why they disagree with you about how you want to respond to immigration in Germany.
