Check if a string is the anagram of another Skat

I'm a fan of anagrams, so given two strings s1 and s2 write a program or function that outputs a truthy value if s2 is an anagram of s1, and a falsey value otherwise (not accounting for spaces and capital letters). 

For example:

Input: s1 = "Anagram"; s2 = "Nag a ram"

true


Input: s1 = "stack overflow"; s2 = "fewer kool cats"

false


Input: s1 = "apple rocks"; s2 = "paler spock"

true


Rules


Program and function allowed. 
Shortest code in bytes wins.
