Forgive me but I don't see how caring or being concerned about one thing precludes being able to feel the same about other things. For example I am worried about events in Ukraine at the moment, but that doesn't mean I am now less concerned about events in Syria.
In fact I have noticed that whenever some issue that either primarily concerns women (like rape), or whenever an issue like violence (which can and does affect us all) is viewed from how it affects women someone inevitably comes along with a "but what about xxxx?" comment.
Maybe the clue to why you perceive feminism as being one sided lies within your own post. Can you imagine how asinine it would sound if when the topic of Ukraine came up someone chimed in "The situation in Ukraine is terrible, but what about Syria?" Both are serious and need tackling, but bringing up one when discussing the other doesn't really help either issue.
By all means you can prioritise certain issues you may believe are more important, but what on earth is wrong with other people trying to discuss and solve issues which are higher on their agenda? If there are other dimensions on violence you feel are more important go ahead and start threads on those.
A frequent one that comes up is breast cancer vs testicular cancer charities. Again by definition a gendered issue, but rather than complain and whine that breast cancer awareness and charity outstrips testicular cancer can't we actually view this as a win and model the success of one to make inroads to improving the other? Thus if you break out of thinking issues have to be adversarial you can take lessons from one and apply it to others.
Anyone that gives their time, effort, thought and energy into improving the world gets my respect and admiration even if they do it on issues I wouldn't prioritise myself. Maybe when we don't have a regular belittling of anything that affects women we won't need feminism quite so much.
