I would say that in casual settings the colours matter a lot. I haven't heard of a red casual deck that is disruptive (i.e. a stax build) and green decks tend to pump out a lot of value on the board. Same goes for Simic although the presence of blue usually means some form of disruption.
I like Esper decks and now that you asked I noticed that surprisingly many of them are proactive even though Esper has probably the best tools for disruption. My
Barrin, Tolarian Archmage deck is definitely a disruptive force with all that bouncing and counterspelling going on.
Rosheen Meanderer is definitely a proactive deck pushing out large Hydras and having very little removal. Just some basic protection. Everything else sort of falls in between with counterspells and removal that can be used either defensively or offensively. Even the
Sen Triplets brew I made recently has very little disruption outside of
Sen Triplets themselves. My friend's
Phelddagrif deck is definitely a disruptive deck despite being a group hug deck, though. It uses counterspells to control the boosted board state and it quickly revolves around them saying yay or nay to your plans.
Then there's of course my
Merieke Ri Berit (which has to be mentioned for its meme value at this point) which is probably an adaptive deck. If it can't find its combo it'll try and stop others from executing their plan. It doesn't run (s)tax other than pillowfort,
Rhystic Study and
Smothering Tithe so it cannot be a true disruptive deck at heart. It's not a proactive deck either with all the removal and counterspelling going on.
All in all I feel like most casual decks are proactive, some are adaptive and very few are disruptive. I think most casual decks can be classified this way - it's just that the proactive end is overrepresented so people probably don't recognise their decks as proactive decks. Very few casual decks actively try to prevent others from winning. Relatively few casual decks even carry the means to shift from proactive to disruption making adaptive strategies pretty rare, too.
There's a stigma to doing disruption. Disruption "doesn't let others play Magic" (which isn't true) so it is usually soft-banned from most groups that I've encountered. Even online, say on Cockatrice, you see "no stax, no MLD, no combo" often tagged in the title of the room. This heavily implies that people don't like disruptive plans and they also dislike proactive decks that can't be interacted with through combat.
