What is the equivalent of "I am risking my head to say" when expressing a different opinion? [closed]

When you are in a minority, say most of the people prefer A to B, if you want to assert your support for B, you can have different moods, e.g.,

(1) brave and combative: "I love B so much more than A, come sue me!!"

(2) cautious I: "Am I the only one supporting B?"

(3) cautious II: In my native language, it is common to say "I am risking my head to say I am for B, not A".

So my question is what's the English equivalent or alternative to "I am risking my head to say" in 3) cautious II above? Thanks.

Solution 1:

You are sticking your neck out!

stick (one's) neck out TFD

To personally assume or expose oneself to some risk, danger, or responsibility; to imperil oneself or put oneself in harm's way.

The figurative interpretation is you are taking a risk, as you risk having it chopped off!

Solution 2:

As FumbleFingers answered in a comment to the question,

I know I'm going out on a limb by expressing my support for B rather than A (figuratively, on a tree branch that might not be strong enough to support my weight).
