Q:

Usage of alternate vs alternative with "equally"

Here's the scenario of the usage:

... doing something is equally alternate to dooming yourself.

or,

... doing something is equally alternative to dooming yourself.

Which is the correct usage? Any other suggestions?
Need an alternative to use like:

... doing something is equally ____ dooming yourself.

Any help?

A:

Grammatically, there is no problem with either. 
But the meaning is unclear in either case.
There are two meanings for "alternate" and "alternative":

X then Y then X then Y .... 

choosing X or Y

I, like many people, use "alternate" for meaning 1, and "alternative" for meaning 2; but some people use them the other way round, or do not make a consistent difference. 
Combining them with "equally": meaning 1 makes no sense at all. Meaning 2 makes a sort of sense, if you mean something like "choosing X or Y, and they are equally attractive choices", but the meaning is very unclear, and I wouldn't advise saying it. 
But I don't think that is what you intend either. I'm not clear enough what you do mean to make an alternative (!) suggestion.
