I do believe meanings have changed over time. The metaphor the Xmen were built on, no longer exists in 2020 and probably hasn't existed for 15 or more years. The Xmen are watered down in their story plight to enlighten.
The Xmen have become stories about space, or increased population or fighting whatever bad-group of the month, they don't fight for equality or any other social injustice. It's not written anymore. The books I have bought had nothing to do with social injustice nor did they foster justice and I haven't bought one in some time. IMO.
Yes, you can say 1960's – somewhere to the 1990's to early 2000's, that metaphor held, I don't think it does anymore and hasn't for sometime. I can't broad stroke (painting metaphor) for what they should represent when the Xmen haven't represented in some time. IMO. I think the Xmen metaphor lost its poignancy and relevance based on writing in the early or mid 2000's. The writers stopped using the metaphor. I'm
not saying its not important, I'm saying the creative people at Marvel changed and with it, so did the Xmen.
I have no problem with diversity or social justice – show it, enlighten people. The media is the best to showcase that and media can do it best but the method with social applications (twitter/facebook/tumblr/etc) was always my issue and I've stated that before. There should be no bullying, online or in person to win the SJW stance, more damage can be done when negligent. I've seen it. That is not an experience to be taken away for philosophy. It's an understanding that to SJW, find the better method. IMO.
Please accept that we understand or experienced some things differently and others have not and that no topic is black and white. There are shades of gray everywhere.
Play nice and I mean that fondly.
