There is only one pony I can say I explicitly hate. Trenderhoof. For leading Rarity on several times and then just jumping right back to Applejack as if to drive another nail into her heart. Before anyone says she does the same to Spike, I’ll admit, it does happen on occasion, but Rarity does show genuine affection and appreciation towards him much more often.
 
As for the princesses, why hate any of them? Luna might be my favorite of the four, but I still love Celestia and Cadence, and I loved Twi long before she was a princess and never raged over that fact (unlike some bronies). All four are kind, compassionate, and responsible leaders leaders.

There’s “Lunabuse”. Is that worth anything?

I went though this same thing when I saw the Celestia Hate tag.
 
I’m not a huge Luna fan. XD

uhm, hey, OP? isn’t it actually much Better that Celestia fans aren’t sinking to the low levels of those particular Luna fans, those that Want to demonize Celestia to make Luna look better by contrast?
 
I’m actually Proud to see Celestia fans are of so much more reasonable.
 
in fact.
 

 
this is most excellent news. Let’s Never sink as to make any Luna hate bullshit..

Damn, that default iOS style for buttons and selects is tacky as hell…
