Lol very true about Muttards, no one cares them.
About Fed you misspelled GOD as GOAT go and correct hour post or I'll report you for misleading information.
About Dulltard I've general observation that they've averaged their IQ around 22.77 which is lower than room temp.
You are on top form lately
Anyway to answer the question, it is between the Nadaltards and Fedtards. Murraytards and Noletards are not that bad, they are no where near on the level of the Fedtards or the Nadaltards. They are not very agressive trolls or cocky. Just delusional. And they are not that big in quantity as compared with the Nadaltards and Fedtards.
Fedtards and Nadaltards are quite terrible, Fedtards infest every Nadal thread with their nonsense/hateful comments, saying about how much a cheater he is, his tennis is disgusting, he has no talent, the courts are to slow, that's the reason he is doing so well, etc. They are vey agressive as well. Nadaltards on the other hand, are quite unbearable as they are they are obsessed with the H2H and bring it up every time, Fed is very lucky because of the weak era nonsense, etc.
It's close imo, but I'll go with the Fedtards. Too obsessed with Nadal.
