I don't see that. The protest group has a place, they appear to be younger, (rightly) angry, possibly with less to lose, possibly in more of a position to take direct, more militant action. They appear to be deliberately anonymous which is a double-edged sword. On one hand they are less accountable and can get away with more. On the other hand, other supporters don't know who they are.
The Trust members and other supporters groups are generally older. They have contacts, experience, nous (most of the national media comments in recent weeks have come from them). They also have careers, families, commitments. They are accountable, not anonymous and may not be as willing to risk arrest if action turns extreme. These are broad generalisations of course.
Both of these factions want the same thing - Martin out.
Now if the protest group go arm in arm with the Trust, they risk their anarchistic reputation and they will arguably lose credibility among their direct peers, who may then be less likely to join them in more extreme action.
The Trust similarly may feel their more diplomatic aims will fall if they are linked too closely with a militant fan group. This is not just dialogue with Ron we're talking about here. It's dialogue with Tom Lawrence, Kevin Maher, MPs, sponsors, suppliers, other supporters groups, the FA. This stuff is all going on.
Even if they don't work directly together, there is room for them to work in tandem as a pincer movement IMO, as long as one group appreciates the place of the other.
And that doesn't mean to say Trust members and supporters groups won't join protests. They have and will.
