Steve often talks about how various people have made LRT look bad, but truth be told when the St. Clair and Spadina "LRTs" were built we were promised fast and frequent service (some councilors said it would be comparable to a subway in speed), now if you have ever taken these lines you know how true that is and why LRT's may not have such a good name. . .
St. Clair and Spadina are quite useful for short trips, in that case the frequency matters more than speed. Pre-covid, sometimes I used to take the St Clair line in order to get from one branch of Line 1 to the other. Bloor was too crowded, going all the way through Union would be boring, while the Sheppard / Wilson / Lawrence buses may have big gaps or get crowded. St Clair streetcar was the best choice; it took ~ 9 min to bridge the 2 km gap, which is technically slow, but in practice I didn't mind because the trip was so short.
Likewise, Spadina streetcar works well if you need to get say from Queen to College. You don't need to wait for long, the streetcar always comes within a few min (unlike the Queen or Dundas streetcars; those are completely unpredictable).
Comparing to the proposed suburban LRTs: indeed the St Clair and Spadina lines are poor examples. The suburban lines will be much faster, primarily because of the wider stop spacing, plus a different built form (greater distances between the traffic light). Who should be blamed for the confusion: the LRT proponents or the opponents, is a matter of debate. Maybe, that's just the generic tendency of the public to equate what they haven't seen to what they have seen.
At least, Steve never makes factually inaccurate claims. He has his preferences, posters here have their own preferences, not all preferences align 100%. That's just fine.
