I can't stand Wintreath, but my personal feelings aren't a good reason to prevent an entire region from opening relations with them, so if everyone else is okay with it then I will vote for it.
If you wouldn't mind perhaps expanding on your reservations? As a citizen-legislator, your voice matters as much as anyone else's. I'd rather see robust debate than an unenthusiastic "yes" from the Ecclesia! 
Well, part of it is the way they were founded, which really shouldn't be an impediment to relations with Taijitu and is just a personal problem I have with them. Wintermoot went on a power trip in Spiritus, ran someone out of the region, and some people (including me) confronted him about it and he ended up resigning the presidency and his citizenship over it. He then left the region and moved to Wintreath, which he claimed was just his puppet dump. Well, not too long later other citizens of Spiritus started moving to "his puppet dump," so basically Wintreath was founded as a schism from Spiritus and by poaching active citizens from Spiritus. Again, that really has no relevance here, but it does impact my personal feelings toward the region as someone active in Spiritus at the time and someone who cares deeply about Spiritus as one of the people who built the region.
The other issue is the fact that Wintreath harbors Govindia, and this might be something Taijitu
will want to consider. Not only do they harbor him, but they generally aren't very respectful of their friends' and allies' desire not to associate with him. There have been disputes about how and when it is appropriate for Govindia to be present during interregional defender operations, for example, with Wintreath at first fairly uncompromising about their insistence that he should be tolerated in the joint defender IRC channel at all times. They've since compromised after more disputes, and Govindia is only permitted in that channel during updates and if he has a specific reason for being there (e.g., a liberation that WHR is cooperating with).
This probably all sounds small. Like I said, I don't think it's a reason for Taijitu not to have relations with them. But I don't like them and the way they interact with other regions, essentially. On the other hand, other regions seem to have had more positive experiences with them.
