>If you choose to read it as "the future is only female" you can do that, but I'm fairly certain that's not how it's meant to be read.

But there are many well-intentioned people that WILL read it as that. And with this I fault the the writer and not the reader.

I think this is one of the biggest problems modern liberal movements have with messaging. And I say this as someone who 100% is in support of "the future is more female than the past, which was predominantly male" and "black lives matter".

I don't think the issue is in the nature of brevity in communication. When these movements create their slogans, their number one goal seems to be motivating and incensing the base of people that already agree with them. It seems that the question is never asked: "how will this messaging come across to people who don't already agree with us?" - let alone, "how can we convince those people to acclimate to our viewpoint?" A shirt that says "the future is only female" seems likely to increase vitriol by pushing away and shutting down well-meaning disaffecteds that might otherwise be convinced of the liberal cause.
