She then suggested that this was because of the shippers looking for 'viability.'

It's comments like that that keep me keeping my distance from that comm! ;)

In any case, I fall into the category of Zutara-shipper who prefers Tokka (though I'm also a Suki fan and like Suki/Sokka). I don't really want to see mutual romantic Tokka in the current Avatar timeframe anyway.

I think a good portion of Zutara fans ship Sukka because it leaves Toph free for Aang.
