You can make that case, but may I suggest, you're not doing a great job of persuasion here..
Let me start w/the notion than when first posting on any forum, its good to introduce yourself. That doesn't mean (in most cases) your real name or job title etc. Its just hi/hello......how long you've been lurking, what about UT interests you.
Opening with a post that could certainly be read as anti-development on a forum that is broadly pro-development is very tough cold open.
From there, may I suggest less use of bold. It has a place, for instance, emphasizing a key point in a post to which you are replying or an article you're discussing, so as to show people your jumping off point. Your use of it reads more as "I am making an emphatic statement for which I have no proof, but because I've bolded it, its unchallengable!"
Its a very assertive way to post. Surely, the point in posting here is not to read your own typing, but to persuade some here, on a forum full of influential folks, many tied to the development process in one fashion or another to lean-in to support your cause, or at least not lean the other way.
To do that, you need spend a bit more time mustering evidence in support of a credible argument. To be clear, if you're a regular lurker here, you'll know I sometimes hold contrarian positions to the majority (but usually ending up bringing them on side) and regardless, I'm happy to entertain contrarian views.
But you need to bring the substance to support them.

Let me help you a bit.......just for the sake of good discussion.
Why is any tall building too tall?
There are potential arguments. These may revolve around any or all of the following:
1) Insufficient infrastructure or services to support the new development (electricity, water/sewer, transit/roads, parks, childcare, school capacity) etc. If you want to use this argument, you need to identify the current capacity of local schools and how many students this developent may bring such that its a problem, or the distance to the nearest park, or how far it is to the nearest current or proposed rapid transit station.
2) The height may cause shadows. Shadows aren't 'evil' but can detract from the enjoyment of a school yard, public park or plaza if they are lengthy, cumulative, or just at the wrong time (example recess or right as school gets out)
Have you looked at the shadow studies to see where the shadows will fall and when?
3) Visual coherence/context/planned context. ie, this will stand out like a sore thumb, this one you do offer some discussion of precedent for.......but here's the thing....is seeing a skyscraper in the distance really something that adversely affects you or your neighbours? I'm going to suggest the answer is 'no'. So....what were' really discussing is how it looks when you're walking by, or across the street. Here, there is a way to 'hide' height by using a podium or base building that meets the street at a height most would find reasonable, typically 3-5 floors, with the towers set-back by several meters from the roofline such that you don't even notice when you're walking by, and only tangentially make note of from across the street. So a discussion on this point is better focused on massing (the way the buildings are shaped and organized rather than height).

I think there's always room to question a proposal or plan on any level, pretty much, for any reason, but its hard to have that discussion if your position isn't well fleshed out and evidence-based.
