It is utterly ill-advised. Software design is about abstraction, to make code modular, flexible, and extensible. It doesn't matter it is OOP or FP. Both approaches have their own advantages and limitations.
The dogmatic answer is misleading. It might be ok to introduce OOP to new programmers, to open a door for programmers who are only familiar with procedural programming. For any experienced programmers, if they don't believe in this dogma, I have to say this is not a right career for them.
