I don't think there's anything inherently wrong with adopting an anti war position, or as close to one as possible given the circumstances.
You say though that you're sceptical of NATO involvement even to the extent of sending weapons. The fact is though that without the intelligence, training and weaponry support provided by the west, you're effectively condemning Ukraine and its people to rule by an oppressive dictatorship, the stripping of its resources by a country that gives zero shits about the human and environmental cost, and the death of anyone connected to maintaining a liberal democracy in the country.
Those are the consequences of not providing support, and those are the consequences
bimble talks about when comparing it to the liberation of her ancestors in WWII.
Fwiw, I wouldn't send NATO troops in, and I don't think you'd find many people on here advocating for that, but the cost of not doing anything and waiting for ineffective sanctions to bite over months and years while the Ukrainian people suffer is high, and you need to own that if it is your position.
