Marksman ≠ ADC
Marksman = {ADC}
Azir is a Marksman, according to Riot. The two characteristics of gameplay that Azir shares with ADC Marksmen is that he is ranged and Autoattack reliant. Azir OBVIOUSLY isn't an ADC so why would Riot classify him as one? You never expressed illicit disapproval of Azir being classified as a Marksman in you previous post by the way.
I asked that question because the message I got from the previous post was that TF shouldn't be named as a Marksman because it's misleading when Azir is named a Marksman and Riot seems okay with it. Again, you never clearly disapproved of Riot classifying Azir as a Marksman, dude, you didn't even name Azir in that post. Why can't Azir be a Marksman when he's got great range and he's autoattack reliant.
I'm still confused why you think that question was abusive in any way. I criticised you for failing to mention Azir and expressing your opinion in why he can't be a Marksman. That wasn't out of malice, that was out of confusion.
Previous to that, you outlined why TF can't be a Marksman mentioning that:
• He's got low range compared to ADCs.
He's got 525 range according to the lol wikia which actually is not that bad, Lucian has 500, Kog'Maw has 500 but of course both have abilities that extend far more. AD TF's range ability (Q) isn't going got deal any damage so TF can only rely on his 525 range to deal crits and physical damage. He's probably disadvantaged here. But again, Marksman does not mean ADC according to Riot so I'm digressing heavily on this point.
• He's squishy.
Every ADC, if you want to compare him to them, is squishy and so is Azir and Kayle and Teemo early in the game.
• He has no instant escape.
A number of ADCs have weak/no escapes Kog'Maw only has his Ooze for its slow to help him escape and that's not even a real escape. Heck TF has his ult to teleport half way across the map. No escape my ass.
Azir has his E to escape/disengage, if soldiers are well placed and used it shuts down ganks quickly and post lvl 6 he has his ultimate great for cock blocking entire teams.
TF, comparatively, has his stun to help him escape and if he's quick enough, he can use his ultimate to escape.
