ASP.NET MVC: Is "views must be dumb" correct statement?

Most of the good references for MVC on web strongly suggest "views must be dumb". It should not contain any logic. This does not seems valid when I try to implement it.

• Some of my views display only first name of student and some of them display only last name and some of them display full name. My database (and POCO and DTO) store name in separate components. I see best place to format the name is view.
• My view changes on some actions on client side without hitting server. Example, on clicking some button, it hides some part of view and shows other and disable some controls. Or another button opens new window and takes some inputs and validates it. This input is never sent to server; it is only useful for some client side activities.
• I have validations on server side. But just to save the hit to server, I also validate on client side.
• Data binding with KnockoutJS.
• Based on data (start and end date) received from server, I generate table on client side to display sections of that period slicing 1 hour each. This is something scheduling like GUI. I need to do date and time calculations in view to achieve this. When I was in stone age (ASP.NET WebForms), I was generating this table on server side; I know you are shocked. I shifted it to JS for performance.
• In SPA, view hold most of the logic by fetching only necessary data from server through AJAX.

I can put many other similar examples here those force me to put some logic in view. Considering that view still holds logic and use of JS is increasing day by day, can we still say "views must be dumb" is a correct statement? Some details explaining the same with respect to points above will help.

Notes:

• Though my question is based on ASP.NET, I am expecting answers referencing to ONLY MVC as a design pattern; no matter what technology I use. So please do not suggest what is another way to do validations. Points above are just to note some of the cases where logic is necessary in view.
• There might be something wrong in how I am implementing above points. Example, some of you may say validating on client side is not necessary at all. But again, I do not want to understand what wrong I am doing with above points. My only point is that, use of JS (and putting logic in views as a result) is increasing.
