In a hopeful manner
Motivated Grammar tweeted as @MGrammar: “Saw people complaining about sentence-modifying ‘hopefully’ (e.g., ‘Hopefully, we'll win’) being ungrammatical. Please stop, it's fine.”
From @ArrantPedantry, this response: “Surprisingly, some people still hold to that rule, but thankfully their numbers seem to be dwindling.”
Stubbornly, this superstition refuses to go away, and sadly, no amount of explanation suffices to wipe it out. Foolishly, Strunk and White perpetuates it. Laughably, people follow it unthinkingly.
But plainly, sentence adverbs, adverbs that modify an entire clause, do exist in English, and oddly, other than hopefully, cause no uproar when they appear.
