I was never really a raging weeaboo. Before I liked anime I hated it with a passion, I learnt every argument against it and used them as often as I could. I then watched Hellsing (curiosity shivved me) and didn't feel any rage, so I stopped hating it and started watching it.
I still agree with most of the arguments I used back then, I just don't irrationally hate anime anymore. I've said some pretty weeaboo shit on occasion, but I've realised instantly afterwards in most cases what the fuck I said and why it was wrong and I often tried to get my words destroyed as a result.
This hobby of mine is something to be ashamed of, for it's associated with many a retard and a fair load of socially unacceptable crap. Learning what Otaku are to the Japanese just reinforced what I felt, I didn't have any friends that liked anime so it never became a big part of my identity as a person; I am a person who happens to like anime, I am not an anime fan first and foremost.
