Left-handed and right-handed

Turkish people are saying about 'Left-handed people are smarter than right-handed people.' I am a right-handed  a person - and what are you?
do you make that's the kind of generalizations you performed?
I think it's an interesting assumption. :)

Left-handed and right-handed

Turkish people are saying that about 'Left-handed people are smarter than right-handed people.' I am a right-handed a person.  <em>(You can also say "I am right-handed.")</em>

And which are you?  <em>(You're either left-handed or right-handed, one or the other, so there's a specific choice involved; use "which" in this case.)</em>
Are those that's the kind of generalizations you make performed?  <em>(Use "are those" with the plural "generalizations".  "To make" is often used with "assumptions".)</em> 
I think it's an interesting assumption. :)

<em>Well done, Seda!  And I eat left-handed and do everything else right-handed...so now I'm confused...</em>
