MV75, anything before G2 _is_ generally considered G1. Goktimus is being informative, it's not his issue if you choose to use your own personal definition. If you choose to use that, you're welcome to, but don't have a swipe at others (yes, I know it's lighthearted) because you feel the need to use a different definition to the fandom in general.
It's not about reading between the lines, "there was no Primus in G1" is factually incorrect. Granted, Gok used 400 words when 20 would have done, but the content of his message is correct.
Me Grimlock!, for future reference, if you're referring specifically to the G1 Cartoon (and excluding the comic), it's better to actually state that you're referring to the cartoon - it makes sure everyone is on the same page as you (:
