Don't minimize the damage that can be done by a step-parent who shares VASTLY different values than you they start teaching it to your child as if they have the right to do so. This is HELL for the child. In one household (household's are frequently dictated by a SM but may potentially either gender) there is one set off rules and in the other something totally different. The child can become resentful, conflicted, confused or just stop trying or caring if it’s impossible to figure out what is right and what is wrong (and they will try). They may feel guilty for allowing themselves to enjoy drinking a soda everyday when other parent only allows one every week.
Does anyone care that a step should be able to tell your child that they must participate in buddists chants, when you are raising them as christian? Imagine having a step fail to take your child to emergency to seek traditional medical treatment for your child’s severe asthma attack because they are christian-scientists, a step throwing a birthday party for your child when you are raising them jehovah’s witness, or giving your child a bahmitzfah if you re catholic all while your ex passively practices no religion?
It's frustrating and unfair when this happens because a step can abuse power and never be accountable like a parent if they behave in a similar objectionable act that the other parent can't control. If no crime was committed against the child by a step, you probably can't go to court and have a judge make an order to make a court order the force the SP to stop especially if the ex claims they allow SP to do it. Ultimately, if the situation isn't resolved, the only way you'll feel you can rescue your children from the SP, is to restrict the custodial time of the other parent at which time you will probably be painted as trying to alienate the child from that parent (and possibly a scorned ex) in the expensive and nasty custody battle that will ensue. You have now entered into the "step parent trap".
Said child will then learn to play one parent (and/or step) against the other and that will leave you wondering what you did wrong and how your child(ren) came to so disregard your rules and the answer will be that well they witnessed their parent allowing a step to disregard your rules as they grew up, so if you couldn't respect it how dare you judge me for not respecting either.
For the record, I believe it's the re-married spouses' responsibility to draw proper boundaries that respect the rights of the other parent, but the reality is that once the relationship has been established on a balance of power that allows a step to have a certain measure of control over the household and/or step-children, trying to change the rules later will probably destroy the marriage.
I’m not picking on any religion (just examples) and I’m not picking on step-parents either, I know plenty of them are angels in disguise who flew in and took on responsibilities that bio parent failed to attend to, and since frequently the only reward a parent and/or step parent will see for their efforts is the accomplishments of the child, the step can be reward for their positive efforts without ever having to be accountable for their bad ones. I hope I haven't offend anyone, but with each passing day, I find it harder and harder to see children get hurt in the middle of these situations.
Anybody catch the 20/20 special on Thursday, August 18, 2005? I’m watching it now, and needing a Kleenex.
All the best to everyone's child(ren), natural and step.
