I think they're limited in what they can achieve. Ultimately, in this country, we can easily outperform, outwork, and outcompete these cosplaying clowns, quite easily in fact. We already do, as per statistics available (even when case matched based on like-for-like family income) and all they can do is cry about their "forgotten race".
You're right that it was bad in 80s, seriously bad. It still is nowhere near that level today. And this is the worst Tommy can do before the weight of his hypocritical posturing (favouring Israeli interests above British ones) causes a self induced collapse of this paper tiger of a movement. Yes, there will be trouble, scuffles, arson etc. but they are no "street by street" threat that can't be managed.
I will add one more thing - the Tommy movement (and its co-opting by zios and coconut smashers) is actually potentially advantageous to us. Their visceral hatred of us helps make it ABUNDANTLY CLEAR to our youth who the people are that seek to grind them into the dirt in professional spheres. I.e. what was hidden before is now clearly manifest. Our youth should now understand the reason that they need to double down on their aspirations and strive for improvement of their society, in order to fight back against these people at every level, not just on the streets. In short, we have less to explain to our own youth as long as these clowns keep doing it for us with these "movements".
