Ahsanallahu ilaykum, I need an advice to know one is upon the manhaj of the salafs, he is not extreme and he is on the right path. As people say that one is extreme iif they are corrected or one tries to do many acts he knows as Sunnah, one tries to avoid some of the worldy affairs that have sins.

Ustadh AbdulAziz al-Haqqan

You are not extreme for acting on what you know of the Sunnah and keeping away from what is sinful. Imam Ibn Baz said that whoever labels the one adhering to the truth as hardline has erred and blundered, because ghuluw is adding onto what Allah legislated, not holding to it.
