is it wrong to call for liberal religionist

to cease from teaching and preaching?
i have called for some liberal religionist to do just that. i have seen some disturbing doctrine that is obviously not biblical, and if someone is teaching another gospel and another Jesus then what the bible teaches, then are we not to speak up?
if we had teachers in our school system that taught that some things according to their own imaginations were ok and we as parents teach the real moral code especially against homosexuality is this not protecting our children?
please understand unity with error is not biblical.

A Tale of Two Sisters

or

The Tragedy of Ecumenical Unfaithfulness

With heart so kind and gentle, And sympathetic eye;

With touching, deep affection, And loyal, tender tie ---

Was LOVE betrothed to DOCTRINE To hold him all her days:

And walk the path of gladness, United in His ways.

Her younger sister also, Had qualities as fair,

Of caring, selfless, kindness, And warmth without compare;

Thus UNITY was drawn to The husband of her youth:

And pledged herself for ever To be the bride of TRUTH.

But TIME, with bitter envy, Across the testing years,

Pursued the slow erosion Of happiness to tears;

Till LOVE began to weary Of DOCTRINE'S pleasant voice,

And UNITY grew cold to The partner of her choice.

Then LOVE began to notice The charms of HERESY,

And awed by his opinions, She wanted to be free:

And UNITY perceived that Her virtues were desired

By many, many others Whose ways she so admired.

At length, two precious unions, So promising, so blest,

Were darkened by delusion, Disloyalty, unrest;

Til came the day of sorrows, And rending vows of youth,

When LOVE divorced her DOCTRINE And UNITY her TRUTH
