I think Hermann Sasse typifies this himself in The Lonely Way.
For some this is way too much to bear specially when family and perhaps income are involved. I do not know how that is solved, there is likely no solution to this dilemma. This we come to realize is not for everyone. For some this is too much pressure to hold, there are other lives involved and these lives have for example, social and economical needs.
However, one must also realize that a doctrine which we may oppose does not float out there in thin air, but the doctrine lives inside the hearts and minds of people. Such people may not fight clean but rather fight your position subtly. You may not know but I have 25+ years of experience in the computing industry and I have learned a very important lesson early in my career: Any technical problem can be solved politically.
By analogy, any theological problem can be solved politically too.
We can not be naive, if our opponent knows well he can not rebut the solid position we hold, he might try to go political on us and thereby undermine in reality the testimony we hold.
Either he tries to intimidate you politically and usually that does not work or he can try to sweeten you up politically too, like flatter you and thereby glory in you.
Psalm 62: 4They only consult to cast him down from his excellency: they delight in lies: they bless with their mouth, but they curse inwardly. Selah.
