Can someone please explain UASF to me (a mid-life, professional who is quite sharp). So I get no UASF signalling, but what then is the point of rejecting blocks that dont signal Segwit?

Is it some kind of soft punishment, or 'statement' for Segwit, i.e. I wont talk to you unless you signal Segwit?

I still dont get it, to what end?

This post is too technical and doesn't help a lay person like myself: https://www.reddit.com/r/Bitcoin/comments/62hipj/antifud_the_bip148_enforcing_client_a_walkthrough/

We still need 95{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} consensus?

Thanks in advance
