Q:

Preposition confusion: "in home" vs "at home"

I want to know the correct preposition to use in 
 this sentence, which I wrote for my writing class assignment. 
I have already received my grade, so I'm not trying to cheat or something.

'...Freedom can also refer to being secure in home and hometown'

Is it correct to use 'in home'? or is it wrong? I know there are alternatives which fit better (e.g: at) but what about 'in'?
I looked this up on the internet but opinions seem to vary significantly.

A:

I can see your logic. If someone is financially secure, they are secure in their finances. You can be secure in your job and secure in the knowledge that someone, somewhere will agree with you. These are common phrases.
Dictionary.com gives the following definitions for "secure" (amongst others):

free from or not exposed to danger or harm; safe
sure; certain; assured: secure of victory; secure in religious belief

If something is "secure at home", that would imply the first definition: it is free from risk. I believe you mean the second definition: "home and hometown" are "assured". Therefore, I don’t think you are wrong to use "in" in this context.
