Let’s not use semantics to get some people off the hook. Punching-down means targeting people in a less privileged position than yourself. Understanding your privilege and another groups hardship is very different from thinking you’re better than those people. By your logic, which I disagree with, I could look at your post and pick you up for using sub-group as the prefix sub, by definition, places something as lesser or smaller then something else. Of course, I wouldn’t, because the logic is idiotic, as is your justification for not liking the term punching-down.
I consider it more a philosophical point than a semantic one. You've ignored the last line of my post and just gone in with the tribal ****e like most people do, and I knew it was coming from someone. At no point have I condoned the comment, so I'm not 'letting anyone off the hook'. I'm deliberately not taking any part in condemning or condoning the original comment. I'm definitely not supporting it and I'm definitely not looking to shame anyone for it either. I've not touched it. I haven't alluded to my thoughts on it other than the fact I questioned the legitimacy of something said against it.
What I don't agree with is the notion of punching down and where I believe it subconsciously comes from. True equality will only come from harmony in my opinion, which stupid comments, nor fighting about them will ever achieve. Personally I believe in individuality, not group identity - I'm just trying to explain my rhetoric.
In terms of 'sub', it literally just means smaller, or off-branching when referring to groups, as you've essentially said yourself... Which is literally what I'm referring to when I talk about sub-groups. There's no alternative superiority suggestion there - it's a fact that sub-groups are smaller than 'groups', plain and simple, smaller meaning in the minority. 'Punching down' however, connotes causing damage from a position of superiority, whether we're talking literally or metaphorically.
In terms of 'privilege' I have no more or less rights than anyone else here, so we must be talking about either 'historic privilege', which is literally history, or instead referring to 'wealth/affluence'. I'm yet to see anyone make a legitimate argument for a single specific special advantage or specific human right that I have that others in the same country as me currently don't, based solely on the colour of my skin. Real advantages purely come from wealth, and thankfully anyone has the ability to become wealthy through a variety of different means. Some are born into wealth, yes, and they tend to have more opportunities to transition into their own wealth. This has nothing to do with ID factors or groups in my opinion. There are wealthy, influential, powerful people from all different backgrounds and religions in the UK.
I've gone on about wealth a bit much there, but I've always found when people talk about privilege that's quickly where it goes to, and as of right now, I'm not convinced there's any other genuine factor that could legitimately be considered as someone having more or less privilege than someone else. I believe anyone has the ability to be the best they can be and 'get theirs' should they have the aspiration and determination to do so. I don't think people are prevented from wealth accrual based on their nationality, skin colour etc.
I shouldn't have to, but I'll clarify again, I'm not saying racism is OK. Best way to be - treat people how you want to be treated and leave it at that.
