seriously... no one really attacks other peoples music choices like you.
You've obviously never encountered toa$t before then! But seriously, most of my 'attacks' are just banter. You're free to like whatever music you want to like. You're also free to take the piss out of my preferred music - one of my best mates in Melbourne used to always take the piss out of Kraftwerk (one of my absolute favourite producers) - whenever I put on their 'Minimum Maximum' DVD, he would always say 'it's just 4 boring old guys standing behind laptops and pressing the play button', and he would always sarcastically ask me 'What instruments are they playing there? - is that a guitar, a saxophone, a keyboard? etc etc etc'. He was into Justice, so obviously I used to give him shit back

But it was all in good humour.
Ok, what do you call those artists, minimal, progressive. Please tell me EDM master.
Why does it annoy you when people refer to all EDM (or 'dance music' as we call it in the UK) as 'techno'? - probably the same reason(s) it annoys me when people refer to the artists you mention as 'electro'. I don't know for sure what genre those artists are in, but it's certainly not electro!
A quick Wikipedia search tells me that:
Crookers is progressive house, electro house, hip house, and fidget house
MSTRKRFT is electro house
Deadmau5 is progressive house, electro house, trance, neo-trance, techno, and house
If you've got a bit of spare time on your hands, you should check out
this article - it's quite an interesting read, and lists many artists it considers to be 'electro' - you should check out some of those artists - I'd be genuinely interested to hear what you think!
Peace
