Most people can see through "I strongly disagree for the following reasons..." as a euphemism for "your idea is stupid, and this is why..." And the more you emphasize "strongly" in the former, the more likely "fucking" materializes between "is" and "stupid" in the latter.

That kind of bland vocabulary makes one's statements sound like limp static. Corporate dialect is contrived to remove strong (corporate-environment-inappropriate) emotion from your speech. If you're well acquainted with your colleagues, then I'd hope you could express yourself more genuinely. You're probably more relatable than a peppy talking head who never offends anyone.
