Agreed, but I put easy, not easier. I suspect we really agree on all points.
If you know C#, it's easy to learn Java, as most the concepts are shared, and even the syntax is very similar. When someone says If you learn to program in one language, it's easy to learn another, it betrays that they don't understand that some languages are similar, but some are very different and have unavoidable learning curves.
C++ is a good example. Learning C++ is not easy, no matter what your background knowledge of other concepts and languages. It's a huge language, in which nothing is simple. Even the build model is a minefield. Having a solid understanding of imperative programming and OOP (from knowing Java, say) is certainly an important head-start. I wouldn't recommend C++ as someone's first programming language. There's still an enormous amount to learn about C++ specifically, no matter your background knowledge.
