I usually try to keep my hatred of Gen 4 in check with my love of Gen 3. I try to redirect my thoughts more positively. 50% of LotE rewrites were all about that. Sometimes it doesn't work and my heart just fills with bitterness.
I don't like ranting about Sinnoh, it's very uncivil of me, no matter how I feel. I'm sure it's uncomfortable even for other people who dislike Sinnoh (and I am forever grateful to those people for validating these feelings of mine).
I would much, much rather spread love of Hoenn than hatred of Sinnoh. So, peace? <3
