In answer to your original question, yes, you can.
But you must be careful, and in personal conversation frame things in questions. Just giving a fact here or a quotation there can get defenses up, and that can come back to bite you in the ass. I've had success in that way.
If you mean in the congregation, answering up, then I think possibly, but you have to be even more careful as the eldubs will be listening too and you don't want to get put on the radar.
If you have to be there (I share your pain bro) then good Christian answers can redirect the hate propaganda sometimes, and can show people that you know what you're talking about scripturally. This could come in handy in the future if word gets out about your doubts, 'brother rogue apparently has doubts? But he's such a knowledgeable brother. Maybe he's onto something...'
