Wait no I change my vote

India was never an island

If the Indian plate can be considered an island, then Australia would be an island too.

YES, AUSTRALIA IS A FUCKING ISLAND, NOT A CONTINENT. OCEANIA IS A CONTINENT

Still India was its own continent in the old days that just ended up merging with another

+ Australia has its own plate

I'd say the Indian landmass before crashing into Asia was around the same size of Greenland, judging by comparisons of Indian borders compared to Greenland

A continent I'd say is a mix of geographical anf cultural lines

Also, if every plate was a continent, then Somalia, the Caribbean, and the Arabian Peninsula are also continents

But the Australian plate is a major plate. The plates you named are minor plates.

Continents are basically just THICC islands

But they're not called islands

But they fit the definition of an island. A landmass surrounded by water

I guess?
